Fix HOpenAL's configure.ac bug that can't find OpenAL framework under Mac OS X
Some people who want to build GHC under Mac OS X platform find that HOpenAL's configure.ac can't find OpenAL framework. And If they compare with some package's configure.ac, they find OpenAL package's configure.ac is different from OpenGL, GLUT and ALUT packages'.

This patch fix Windows bug, too. Because cufigure.ac uses CALLCONV=stdcall on *-mingw32 case, although it has comment like this: "NOTE: For some obscure/unknown reason, OpenAL uses ccall, even on WinDoze...".
