This fixes a failure in 'make check' found by the tinderbox when trying to build this code on Linux/ppc. This code is only designed to run on Intel platforms, so don't even bother building it if we're not in that set.
Looks reasonable to me, except it should probably be checking $target_os (cross-compile target) rather than $host_os (cross compile build host).
I think you are misunderstanding the variables (or perhaps you are following Mozilla's usage of the variables, which is wrong but internally consistent).
CBUILD - The platform of the machine being built on. CHOST - The platform that the delivered product will run on. CTARGET- The platform that the delivered product will generate code for.
CTARGET is only really relevant for toolchain packages.
eg. I want to build a gcc that builds mips code and runs on my intel box: CTARGET=mips-* CHOST=i686-*
If I want to do the building of that compiler on my ppc box: CBUILD=powerpc-* CTARGET=mips-* CHOST=i686-*
