Log Message:
In the libtool configure script, the basename of the compiler is used
to make decisions about which compiler is being used (gcc, SunPro, etc).
To make this function "correctly" in the presence of the compiler wrapper
scripts, we need to extract the actual compiler command from the wrapper
frame work.  So adapt the section in the configure script which already
attempts to deal with some other compiler wrappers to deal with the pkgsrc
wrappers.

This should address PR pkg/33467 and PR pkg/34581.

Bump PKGREVISION.
