autoconf 2.66 breaks building pkg-config

[mmadia]

Haiku-r37444-2hybrid
 autoconf 2.66 introduced a regression; confirmed by installing v2.65.

Another issual is that AX_CHECK_GL (defined in m4/ax_check_gl.m4), taken from autoconf-archive upstream  http://www.gnu.org/software/autoconf-archive/

checks for -lm when it wants OpenGL
 http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob;f=m4/ax_check_gl.m4;hb=HEAD

It's a defect?

autoconf-2.67 is out, there were a few testsuite failures, but might be working as well as 2.65:

fixed in r930.
