[Crash-utility] [PATCH] build sial with TARGET_CFLAGS

[Rabin Vincent]

On an x86-64 host, crash TARGET=ARM gets built with -m32 but sial
currently doesn't, leading to the .so not being loadable:

    crash> extend extensions/sial.so
    extend: ./extensions/sial.so: machine type mismatch: 62
    extend: ./extensions/sial.so: not an ELF format object file

This patches fixes this by using TARGET_CFLAGS in the sial makefiles.
This should also take care of PPC64 which currently explicitly passes
-m64.
