Fix alpha, powerpc build failures.
* acinclude.m4 (GLIBCPP_CHECK_MATH_SUPPORT): Substantially
re-write. Need to check for both proper declaration when using a
c++ compiler, and "C" linkage when linking. Do both, and if both
exist, then define the HAVE_* bits in config.h.
(GLIBCPP_CHECK_MATH_DECL_AND_LINKAGE_n): New, uber-macros. Does all.
(GLIBCPP_CHECK_LINKER_FEATURES): Actually link and run this
program, doh.
