Fix libGL.a check on configure

[Anderson Lizardo]

Hi,

Changelog:

Fixed the libGL.a configure check for systems where
/usr/X11R6/lib/libGL.so is a symbolic link.


PS.: I've not used a simple "test -e" because
http://www.winehq.org/hypermail/wine-patches/2002/01/0206.html says this
does not work on Solaris.
