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.

michael@241 50 GNU zip (gzip) is a compression utility designed to be a replacement
michael@241 51 for the traditional Unix utility compress(1). Its main advantages
michael@241 52 over compress(1) are much better compression and freedom from
michael@241 53 patented algorithms. gzip produces files with a .gz extension.
michael@241 54 gunzip can decompress files created by gzip, compress and pack. The
michael@241 55 detection of the input format is automatic. The format of the .gz
michael@241 56 files generated by gzip is described in RFCs (Request For Comments)
michael@241 57 1951 and 1952.
