Wed Mar 4 08:04:31 UTC 2020
Activate already existing mesa3d solution for the isinf compile
failure for uclibc based toolchains instead of using a custom
workaround.
- remove 0005-src-gallium-drivers-nouveau-codegen-nv50_ir_ra.cpp-p.patch
- add 0004-c99_math-import-isinf-for-uclibc-based-toolchains.patch

Notes:
- as Romain Naour pointed out ([1]) the existing check in
c99_math.h failes for uclibc (because it impersonate glibc-2.10),
so enable the original uclibc isinf solution instead of the
custom work around
