    intl: Add --enable-host-shared support [PR100096]
    
    As mentioned in the PR, building gcc with jit enabled and
    --enable-host-shared doesn't work on NetBSD/i?86, as libgccjit.so.0
    has text relocations.
    The r0-125846-g459260ecf8b420b029601a664cdb21c185268ecb changes
    added --enable-host-shared support to various libraries, but didn't
    add it to intl/ subdirectory; on Linux it isn't really needed, because
    all: all-no
    all-no: #nothing
    but on other OSes intl/libintl.a is built.
    
    The following patch makes sure it is built with -fPIC when
    --enable-host-shared is used.

            * configure.ac: Add --enable-host-shared support.
            * Makefile.in: Update copyright.  Add @PICFLAG@ to CFLAGS.
            * configure: Regenerated.
