Fix match patterns for cegcc*.

[Ralf Wildenhues]

In Libtool, we commonly match $host names with a trailing '*' to allow
for (present or future) version numbers, on the grounds that most
systems remain compatible with their older versions, and to let Libtool
code require fewer changes.

I'm thus pushing this to match more uniformly for cegcc.

Cheers,
Ralf

        Fix match patterns for cegcc*.

        * libltdl/config/ltmain.m4sh (func_mode_link): Match '*cegcc*'
        instead of '*cegcc' for $host_os.
        * libltdl/m4/libtool.m4 (_LT_CHECK_MAGIC_METHOD): Likewise.
        * tests/lt_dladvise.at (lt_dlopenadvise library loading):
        Likewise.
        * libltdl/m4/ltoptions.m4 (AC_LIBTOOL_DLOPEN): Match
        '*-*-cegcc*' for $host.
