build failures after stdlib update

[Alexander Best]

so is there no way to fix this? this is what i've tried and still the problem
exists:

1. backup /etc
2. `wget -r
ftp://ftp.allbsd.org/pub/FreeBSD-snapshots/amd64/9.0-HEAD-20100222-JPSNAP/ftp/base/`
(this shnapshot shouldn't contain the libc bug)
3. then i ran the install.sh script in that directory
4. and replaced /etc with the backup version

yet gcc still segfaults during buildworld. :(

thanks go out to delphij, nox---, jilles, garrcoop, x6b and joerg on #bsddev
for helping me with this problem. :)
