cobol: Restrict COBOL to supported Linux arches [PR119217]

The COBOL frontend is currently built on all x86_64 and aarch64 hosts
although the code contains some Linux/glibc specifics that break the build
e.g. on Solaris/amd64.

Tested on Linux/x86_64 and Solaris/amd64.

	* configure.ac: Restrict cobol to aarch64-*-linux*,
