x86, gcc-4.6: Use gcc -m options when building vdso
commit de2a8cf98ecdde25231d6c5e7901e2cffaf32af9 upstream.
The vdso Makefile passes linker-style -m options not to the linker but
to gcc. This happens to work with earlier gcc, but fails with gcc
4.6. Pass gcc-style -m options, instead.
Note: all currently supported versions of gcc supports -m32, so there
is no reason to conditionalize it any more.
