Make the checks for macro weak symbols be equivalent to the checks for weak symbols. Also fix up several OSHMEM configure checks: * fix an errant AC_MSG_REQUEST * don't check for profiling ability during configure options checks. Instead, defer it to later, when we have weak symbol check results. * don't directly call _FOO macros from the top level * make setting up OSHMEM profiling similar to MPI profiling: create OSHMEM_SETUP_PROFILING macro * cache the results of checking for macro weak symbols (for parity with the weak symbol check -- although we should really revisit/audit the whole cache-checking scheme throughout all m4 code; it may well be inconsistently used) * add some more [] m4 quoting, even in the original C weak symbols test * style: fix some whitespace errors Refs trac:4868 This commit was SVN r32590.
