mesa: Optionally build a dricore support library (v3)

This an adds --enable-shared-dricore option to configure. When enabled, DRI modules will link against a shared copy of the common mesa routines rather than statically linking these. This saves about 30MB on disc with a full complement of classic DRI drivers. v2: Only enable with a gcc-compatible compiler that handles rpath Handle DRI_CFLAGS without filter-out magic Build shared libraries with the full mklib voodoo Fix typos v3: Resolve conflicts with talloc removal patches Signed-off-by: Christopher James Halse Rogers <christopher.halse.rogers@canonical.com>
