Buildroot commit 8f69974c20fbc7dc642be62a0ef3fb2941f5bb35 switched the
buildsystem of mpv from waf to meson but forgot to remove a patch which
fixed a waf-related build error.

-Subject: [PATCH] Work around bool type redefinition by altivec
-
-On powerpc64le, the SDL header may include altivec.h and this
-(combined with -std=c99) will cause a compile failure due to bool
-being redefined as a vector type.
-
-Adjust the compiler flags to add -std=gnu99 (which is compatible with
-altivec) when using gcc. The generic flag '-std=c99' is left in place for other
-compilers (in the gcc case it is overridden by the (later) gnu flag).
