commit 652c50a2541d703fa1fccc04e7b23da06e0dd177
Author: Joel Brobecker <brobecker@adacore.com>

    Use ../libiconv/[...]/libiconv.a instgead of using -liconv.
    
    On Tru64, we noticed that there is a problem with linking against
    the in-tree libiconv when available: The linker does not recognize
    archives as libraries when linking with -liconv.  So, we have to
    use the path/to/libiconv/lib/libconv.a explicitly on the command
    line instead.  Since the latter should work on all platforms,
    we now always use the .a when linking with the in-tree libiconv.
    
    gdb/
            * acinclude.m4: Link against in-tree libiconv by adding
            libiconv.a to the LIBS instead of using -liconv.
            * configure: Regenerate.
