Subject: [PATCH] wscript: substitute cplugins linker flag for macOS
 compatiblity

For an unknown reason, '-Wl -export-dynamic' doesn't work anymore
on the last macOS build (10.12.3 with Apple LLVM 8.0.0) so forcing
cplugins is useless because the check fails. Replacing the linker
option with its substitute '-rdynamic' do the trick.

The syms module from waf still works as expected and only the
symbols specified in mpv.def are exported.
