Should use sofile instead of soname.

Should use sofile instead of soname.

If soname is used here, nm cannot find the file if non-default
toolchain is used.

Hi,

During the use of GN for our purpose, I found issue on gcc_toolchain.gni.  nm
does not get proper filename if non default toolchain is used.

Will you review it?
Thank you in advance,
