[PATCH] libtool.m4: Fix AC_CHECK_PROG usage

In commit:

https://git.savannah.gnu.org/cgit/libtool.git/commit/m4/libtool.m4?id=3D64b=
ef5ba65f6820cd5f88e5249324b4f5955ee25

AC_CHECK_TOOL was changed to AC_CHECK_PROG however the arguments are
different and this result is a value of ":". Change this to match the
original intent.

The lack of FILECMD was causing failures for mips64 builds as -m elf was
being passed to LD which isn't supported on our targets.
