[libgcc, build] Suppress some warnings for soft-fp files


Uros prompted me to look into why we were still getting warnings
compiling the soft-fp code in libgcc despite this in config/t-softfp:

$(soft-fp-objects) : INTERNAL_CFLAGS += -Wno-missing-prototypes -Wno-type-limit
s

It turned out that soft-fp-objects still included the $srcdir prefix.
It seems my libgcc migration missed some chunk of code to strip that,
although I still see the warnings on the 4.6 branch (i.e. before the
migration).

Anyway, the following patch fixes this.  Bootstrapped without
regressions on i386-pc-solaris2.11 and x86_64-unknown-linux-gnu and
verified the warnings are indeed gone.

Ok for mainline?
