Okay -print-multiarch is only in gcc 4.6 of debian unstable, Ubuntu has a
messed up gcc 4.5 without the print-multiarch option.
Then I don't care. Sorry. You don't break 20-year-old conventions and
invent new toolchain options without bothering to contact upstream gcc.

this would be missing the '/lib' as print-multiarch only prints the host
triplet.. (yeah to breaking cross compilation)
It us added later, compare these:
$ gcc -print-multiarch # on Debian unstable
x86_64-kfreebsd-gnu
$ gcc --print-multi-os-directory # on Fedora
../lib64
