[PATCH] Fix crash in libcc1

[Tom Tromey]

The gdb tests of the libcc1 plugin have been failing lately.  I
tracked this down to a crash trying to access an enum's underlying
type.  This patch fixes the crash by setting this type.

        * libcc1plugin.cc (plugin_build_enum_type): Set
        ENUM_UNDERLYING_TYPE.
