解决
OK, after wondering if gcc-config does anything
besides spit out the names of compilers, I figured out I could do this:
root@isuck:~# gcc-config i686-pc-linux-gnu-4.3.2
* Switching native-compiler to i686-pc-linux-gnu-4.3.2 ...
* Your gcc has a bug with GCC_SPECS.
* Please re-emerge gcc.
* http://bugs.gentoo.org/68395
>>> Regenerating /etc/ld.so.cache...
[ ok ]
* If you intend to use the gcc from the new profile in an already
* running shell, please remember to do:
* # source /etc/profile
So now I am emerging gcc again, as it asked me to. It appears to be
going well. I shall report again when I have more info.
