Kostya Serebryany 9d91336a83 [compiler-rt] adjust platform_limits_linux.cc #include of posix_types 
Summary:
Hello,

Building a recent gcc on a powerpc-linux system advertsing:

 Red Hat Enterprise Linux Server release 5.10 (Tikanga)

we stumbled on a compilation error on a file originating
from compiler-rt/lib/sanitizer-common.

sanitizer_platform_limits_linux.cc #includes asm/posix_types.h,
which, on our system, uses __kernel_fd_set and associated macros.
These aren't defined at the point of their use, and the compilation
fails with symptoms like:

  In file included from ../../../../src/libsanitizer/sanitizer_common/sanitizer_platform_limits_linux.cc:29:0:
  /usr/include/asm/posix_types.h:72:51: error: '__kernel_fd_set' has not been declared
  static __inline__ void __FD_SET(unsigned long fd, __kernel_fd_set *fdsetp)
  ...

The attached patch is a suggestion to fix this, by including linux/posix_types.h
instead of asm/posix_types.h. linux/posix_types defines the necessary types and
macros, then #includes asm/posix_types.h.

We have been using it locally for gcc without problems for a couple of years
on powerpc, x86 and x86_64-linux platforms. It is still needed for gcc-6 on
our powerpc host and applies cleanly on the compiler-rt trunk.

Comments ?

Thanks much in advance for your feedback,

With Kind Regards,

Olivier
