[Buildroot] [git commit] package/libnss: fix build failure on RHEL 7

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=fe4b47a12181b89eecb9a8e324f1ad053147f948
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

-DLINUX flag was passed to OS_CFLAGS instead of DEFINES, but OS_CFLAGS
is only used when cross-compiling, not when native building.

Add patch to fix build failure on RHEL 7 host by substituting OS_CFLAGS
with DEFINES.
