perl: Run make depend to fix build race condition

Run make depend before building perl. This fixes parallel build failures
on machines with a high number of cores.

Example error 1:

    /bin/ln -s /build/staging_dir/hostpkg/usr/bin/generate_uudmap generate_uidmap
    make[5]: ./generate_uudmap: Command not found
    make[5]: *** [Makefile:321: bitcount.h] Error 127

Example error 2:

    /bin/ln -s /build/staging_dir/hostpkg/usr/bin/generate_uudmap generate_udmap
    ./generate_uudmap uudmap.h bitcount.h mg_data.h
    /bin/ln: failed to create symbolic link 'generate_uudmap': File exists
    make[5]: *** [Makefile:325: generate_uudmap] Error 1
