F77 hidden sysdeps (was: Solaris whole_archive update)

[Ralf Wildenhues]

This is from an older Solaris thread.  I am sorry for seeming to talk to
myself.

I know of at least one compiler that barfs without this (PGI pgf90),
unless FFLAGS are added when linking a Fortran shared lib into a C
program.  However, I feel very uncomfortable putting such a wide-ranging
patch into stable branch-1-5, because of the unknown implications for
other compilers.  I also believe with proposed F90/FC support this will
be important for other compilers as well.  I have tested this on a few
platforms.

Since branch-2-0 will have another alpha:  OK to apply the following to
HEAD and branch-2-0?

Ralf

        * m4/libtool.m4 (_LT_LANG_F77_CONFIG): Call _LT_SYS_HIDDEN_LIBDEPS.
