GCC Broken - C Compiler cannot create executables

[EdwardAtGentoo]

I'm unable to emerge anything on my system anymore. Any help would be appreciated.

Here is an example of the error I get while trying to re-emerge sed:

checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for x86_64-pc-linux-gnu-gcc... x86_64-pc-linux-gnu-gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.

Here is the config.log from that error:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by sed configure 4.2, which was
generated by GNU Autoconf 2.61. Invocation command line was

$ ./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --libdir=/usr/lib64 --bindir=/bin --enable-acl --enable-nls

What's the output of

[Mike Hunt]

... and

[EdwardAtGentoo]

[alunduil]

Did you already change the GCC profile with the gcc-config command? And then did you source /etc/profile?
