>Description:
On 1.7.22 of cygwin, libtool-base's configure script detects fortran compiler,
FC and F77, and generates wrong libtool is generated.
The libtool script breaks dll files (on cygwin64) or does not link object
files with error (on cygwin).

The wrong libtool script has empty postinstall_cmds, soname_spec etc.
        
>How-To-Repeat:
$ cd pkgsrc/devel/libtool-base
$ bmake configure
$ less work/libtool-base*/libtool
and see postinstall_cmds, soname_spec etc.
        
>Fix:
        
With CONFIGURE_ENV, fortran support is not disabled.
CONFIGURE_ARGS helps this problem.

I want to commit this patch.
I request OWNER's review.
