Re: build failures after stdlib update

i don't think conf/112997 and the issue where gcc segfaults are directly
related to each other:

1. if CPUTYPE is set to 'native' your patch uses `gcc -v -x c -E -mtune=native
/dev/null -o /dev/null 2>&1 | grep mtune | sed -e 's/.*mtune=//'` to determine
gcc's idea of the appropriate -mtune value. that command however segfaults. so
this doesn't really help.

2. i wasn't able to reproduce your `make -V MACHINE_CPU -DCPUTYPE=native`
examples. for me `make` prints the same no matter what CPUTYPE is set to:

otaku% make -V MACHINE_CPU -DCPUTYPE=native
amd64 sse2 sse
otaku% make -V MACHINE_CPU -DCPUTYPE=nocona
amd64 sse2 sse
otaku% make -V MACHINE_CPU -DCPUTYPE=i386
amd64 sse2 sse
otaku% make -V MACHINE_CPU -DCPUTYPE=lalalala
amd64 sse2 sse

..oh and of course i ran these commands with no CPUTYPE set in make.conf. ;)
