V3 PATCH: Don't try to compile libmath/(expf|atan2f).c

[Gabriel Dos Reis]

This patch -- applied to mainline and branch -- fixes a bootstrap
failure on solaris.

Bootstrapped and tested on i686-pc-linux and solaris-2.6.

	* acinclude.m4: Don't AC_REPLACE_MATHFUNCS expf and atan2f.
	* aclocal.m4: Regenerate.
	* configure: Same.
