Replacing arch specific make.conf files with patches for the fallback make.conf which should be applied in the ebuild.
Add a helper script to update patches if the main make.conf is changed. svn path=/main/trunk/; revision=2987

++# -mcpu=<cpu-type> for PowerPC systems selects the type of processor you want
++# to optimize your code for. Code generated under those options will run best
++# on that processor, and may not run at all on others.
++#
++# GCC 3.4 supports many powerpc processor types including: 401, 403, 405,
++# 405fp, 440, 440fp, 505, 601, 602, 603, 603e, 604, 604e, 620, 630, 740, 7400,

++# and rs64a
++#
++# Recommended settings for GCC 3.4 only :
++#
++# -maltivec enables optional altivec support and should be used
++# only for G4 processors, on GCC 3.2 or newer. It also requires that you have
++# the alitvec option compiled into your kernel to take full advantage of this
++# feature. Note: you should also include -mabi=altivec flag if using this
++# option.
++#
++# The newer gcc has a stricter aliasing ruleset that makes type punned
++# expression faulty compiled if -fstrict-aliasing is enabled.
++# That option is implied by -O2 -Os and -O3. Make SURE you don't have that
++# option enabled by adding -fno-strict-aliasing to your CFLAGS and CXXFLAGS
++#
++# Long term testing has shown that -O3 opts can be unreliable on G4's but work
++# on G3 series processors or earlier.
++#
++# The following is the suggested CFLAGS for a generic G4 cpu
++#
++#CFLAGS="-O2 -pipe -mcpu=G4 -maltivec -mabi=altivec -fno-strict-aliasing"
+ #

++# All non G4 PPC boxen should choose this next option. It will work fine for
++# all G3 and pre machines. (note it will not hurt pre G3 machines either to
++# use this mcpu option as it is the default for gcc 3.2.x anyway)
++#
++#CFLAGS="-O3 -pipe -mcpu=G3 -fno-strict-aliasing"
++
++# Recommended settings for GCC 2.95.3 only (Gentoo 1.2 or older):
++#
++# PowerPC 750 > up: this works on G3's and G4s, gcc 2.95.3 doesn't make the
++# distinction between G3 and G4, so this is fine for all NewWorld machines, if
