Rework package yet again, correcting and introducing new buildconf logic:
Conditionally disable bootstrap stage comparison correctly, correct
english grammar, better find system as(1) and ld(1), indotruce detailed
optimization option messages, more completely guess cpu types, allow
profiled bootstrapping without a preinstalled GCC because many other
compilers have long since implemented 64-bit arithmetic, instruct make
to build sequentially (not in sparallel) when building a profiled
bootstrap as GCC online documents recommend, and generally improve
comment blocks.

The single most important correction in this changeset relates to the
GCC changed optimization policy since at least GCC 4.5, in which -march
is always passed and not always correctly guessed. In the case of this
package, allowing GCC to guess the architecture leads to wild build
errors at various subcomponents (zlib, libgcc, libiberty...) and
bootstrap stages. It seems quite platform specific, and the safest
approach to correcting this seems to be explicitly always specifying the
-march argument when bootstrapping GCC. Because the best choice 'native'
is not available when bootstrapping using a foreign (non GCC) compiler,
a guess is made according to rpmmacros l_platform in that case.

It is questionable as to whether these recent optimization changes
on the part of GCC or this package are compatible with each other,
or if either are complete or correct at all. At least applying these
corrections allows this package to build again in most cases test.

 .IX Title "RELEASE 8"
 .TH RELEASE 8 "OpenPKG" "RELEASE(8)" "OpenPKG"
 .SH "NAME"
 \&\fBopenpkg release\fR \- OpenPKG Release Utility
 .SH "SYNOPSIS"
 .IX Header "SYNOPSIS"
 \&\fBopenpkg release\fR [\fB\-F\fR|\fB\-\-fmt\fR \fIformat\fR]
 .SH "DESCRIPTION"
 .IX Header "DESCRIPTION"
 The \fBopenpkg release\fR command displays the OpenPKG release tag and
 distribution \s-1URL\s0. The release tag uniquely identifies an OpenPKG
 distribution and the distribution \s-1URL\s0 is the location where the
 distribution packages and indices are stored.
 .SH "OPTIONS"
 .IX Header "OPTIONS"
 .IP "\fB\-F\fR, \fB\-\-fmt\fR \fIformat\fR" 4
 .IX Item "-F, --fmt format"
 The output format specification. The argument \fIformat\fR is an arbitrary
 string which can contain the special expansion constructs "\f(CW%t\fR\*(L" for
 expanding the release tag, \*(R"\f(CW%u\fR\*(L" for expanding the distribution \s-1URL\s0
 and \*(R"\f(CW\*(C`\en\*(C'\fR" for expanding an embedded newline character.
 The instance \s-1UUID\s0 information is also availble by expanding
 \&\f(CW%r\fR to \s-1UUID_REGISTRY\s0, \f(CW%i\fR to \s-1UUID_INSTANCE\s0, \f(CW%p\fR to \s-1UUID_PLATFORM\s0.
 The default \fIformat\fR is "\f(CW\*(C`OpenPKG\-%t %u\*(C'\fR".
 .IP "\fB\-r\fR, \fB\-\-release\fR \fIrelease\fR" 4
 .IX Item "-r, --release release"
 The package "\f(CW\*(C`Release\*(C'\fR" header value to use for deriving the release
 tag. The values in the \fI@l_prefix@/etc/openpkg/release\fR file and the
 "\f(CW\*(C`Release\*(C'\fR" header of the bootstrap package \fBopenpkg\fR are ignored if
 this option is used.
 .SH "FILES"
 .IX Header "FILES"
 .IP "\fI@l_prefix@/etc/openpkg/release\fR" 4
 .IX Item "@l_prefix@/etc/openpkg/release"
 This optional configuration file can be used to explicitly set values
 for the OpenPKG release tag and distribution URLs. It consists of lines
 with variable name/value pairs. The following configuration variables
 are recognized:
 .RS 4
 .IP "\fBTAG=\fR\fItag\fR" 4
 .IX Item "TAG=tag"
 The default \fItag\fR is automatically derived from the "\f(CW\*(C`Version\*(C'\fR" header
 of the OpenPKG bootstrap package \fBopenpkg\fR. One usually only sets this
 explicitly to a value if a bootstrap package is used from a foreign
 distribution version.
 .IP "\fBURL=\fR\fIurl\fR" 4
 .IX Item "URL=url"
 The fully-qualified distribution \s-1URL\s0 based on either the "\f(CW\*(C`ftp\*(C'\fR\*(L",
 \&\*(R"\f(CW\*(C`http\*(C'\fR\*(L" or \*(R"\f(CW\*(C`file\*(C'\fR" \s-1URL\s0 schemes. If \fIurl\fR contains a trailing
 "\f(CW\*(C`/*\*(C'\fR", this is expanded according to the \fItag\fR value of the \fB\s-1TAG\s0\fR
 variable and the corresponding filesystem layout on \f(CW\*(C`ftp.openpkg.org\*(C'\fR.
 The default \fIurl\fR is "\f(CW\*(C`ftp://ftp.openpkg.org/*\*(C'\fR".
