Comment:

 The real error seems to be:

 {{{
 /usr/include/sys/stdio.h:39:52: error: expected a platform name, e.g.,
 'macosx'
 }}}

 The log is difficult to read because this error occurs repeatedly, and
 because a parallel build is happening, the multiple error messages are
 being interleaved. The build system then fails to recognize that the build
 has failed, and proceeds anyway to the destroot phase, which repeats the
 failing build.

 I can reproduce this problem on my Yosemite system, even with a serial
 build. The error I see is:

 {{{
 /usr/include/sys/stdio.h:39:80: error: expected a platform name, e.g.,
 'macosx'
 int renameat(int, const char *, int, const char *)
 __attribute__((availability(1,introduced=10.10)));
 ^
 }}}

 This is now sounding familiar. OS X's headers use defines like 'macosx'
 and 'ios', but irsim's build redefines 'macosx' to '1' which breaks
 everything. We encountered this two years ago in #36250 and thought we
 fixed it...

 Ah, I see: we applied the patch only on OS X 10.8. We should have applied
 the patch on OS X 10.8 and later.
