Looking at the generated shell script (also the autoconf manual), it
seems AC_SEARCH_LIBS() m4 macro does not define HAVE_LIBsomething C
preprocessor macros, unlike AC_CHECK_LIB() which does define them.
This previous change effectively killed building with GMP because
building that mode depends on existence of HAVE_LIBGMP. [Bug #13402]
