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.

138 .SH "DESCRIPTION"
139 .IX Header "DESCRIPTION"
140 The \fBopenpkg release\fR command displays the OpenPKG release tag and
141 distribution \s-1URL\s0. The release tag uniquely identifies an OpenPKG
142 distribution and the distribution \s-1URL\s0 is the location where the
143 distribution packages and indices are stored.
144 .SH "OPTIONS"
145 .IX Header "OPTIONS"
146 .IP "\fB\-F\fR, \fB\-\-fmt\fR \fIformat\fR" 4
147 .IX Item "-F, --fmt format"
148 The output format specification. The argument \fIformat\fR is an arbitrary
149 string which can contain the special expansion constructs "\f(CW%t\fR\*(L" for
150 expanding the release tag, \*(R"\f(CW%u\fR\*(L" for expanding the distribution \s-1URL\s0
151 and \*(R"\f(CW\*(C`\en\*(C'\fR" for expanding an embedded newline character.
152 The instance \s-1UUID\s0 information is also availble by expanding
153 \&\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.
154 The default \fIformat\fR is "\f(CW\*(C`OpenPKG\-%t %u\*(C'\fR".
155 .IP "\fB\-r\fR, \fB\-\-release\fR \fIrelease\fR" 4
156 .IX Item "-r, --release release"
157 The package "\f(CW\*(C`Release\*(C'\fR" header value to use for deriving the release
158 tag. The values in the \fI@l_prefix@/etc/openpkg/release\fR file and the
159 "\f(CW\*(C`Release\*(C'\fR" header of the bootstrap package \fBopenpkg\fR are ignored if
160 this option is used.

162 .IX Header "FILES"
163 .IP "\fI@l_prefix@/etc/openpkg/release\fR" 4
164 .IX Item "@l_prefix@/etc/openpkg/release"
165 This optional configuration file can be used to explicitly set values
166 for the OpenPKG release tag and distribution URLs. It consists of lines
167 with variable name/value pairs. The following configuration variables
168 are recognized:
169 .RS 4
170 .IP "\fBTAG=\fR\fItag\fR" 4
171 .IX Item "TAG=tag"
172 The default \fItag\fR is automatically derived from the "\f(CW\*(C`Version\*(C'\fR" header
173 of the OpenPKG bootstrap package \fBopenpkg\fR. One usually only sets this
174 explicitly to a value if a bootstrap package is used from a foreign
175 distribution version.
176 .IP "\fBURL=\fR\fIurl\fR" 4
177 .IX Item "URL=url"
178 The fully-qualified distribution \s-1URL\s0 based on either the "\f(CW\*(C`ftp\*(C'\fR\*(L",
179 \&\*(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
180 "\f(CW\*(C`/*\*(C'\fR", this is expanded according to the \fItag\fR value of the \fB\s-1TAG\s0\fR
181 variable and the corresponding filesystem layout on \f(CW\*(C`ftp.openpkg.org\*(C'\fR.
182 The default \fIurl\fR is "\f(CW\*(C`ftp://ftp.openpkg.org/*\*(C'\fR".
