Previously we had a mix of uses of AC_CHECK_PROG[S] and AC_PATH_PROG[S]. The only difference between those macros is that the latter emits the full path to the program it finds, eg "/usr/bin/prove", whereas the former emits just "prove". Let's standardize on always emitting the full path; this is better for documentation of the build, and it might prevent some types of failures if later build steps are done with a different PATH setting. I did not touch the AC_CHECK_PROG[S] calls in ax_pthread.m4 and ax_prog_perl_modules.m4. There seems no need to make those diverge from upstream, since we do not record the programs sought by the former, while the latter's call to AC_CHECK_PROG(PERL,...) will never be reached.
