[vlc-devel] [PATCH] contrib: aom: fix lib pthread linkage

[Victorien Le Couviour--Tuffet]

Fixes android NDK 17 build: the pthread library (as well as the math and
dynamic loading ones) are builtin parts of the standard C library for
android (Bionic), therefore linking against those generates linker error.
