Temporarily disable building the armv7 variants of profile_ios on
...
darwin.
After talking with Jim Grosbach pretty extensively, he was OK with me
punting on this to the Apple folks.
We agreed that the correct fix is either to extend the fake SDK headers
in compiler-rt to support the rest of libc needed by GCDAProfiling.c or
to teach the make build to test for the existence of a suitable SDK on
the system prior to building it. Both of these require someone with
access to the SDK which I don't have, and the latter (my preferred
solution) requires understanding the strange compiler-rt make build
system. Punting to Dan Dunbar or one of the others who support this
stuff on ios to write the appropriate fix, and we can let the build bots
proceed in the mean time.

Bill, I'm not at all confident of the change for Darwin and iOS, but as
discussed we're completely blocked on fixing this. Anyways, please
review and let me know if this will work for you guys. If necessary,
I can work with you to rig up an errno.h stub for Darwin, but I expect
that to be... moderately challenging.

Address a few of the issues in GCDAProfiling I noted when looking
...
through Bill's patch:
1) Correctly test the file descriptor after the sceond attempt at
creating the file.
2) Make the filename a global so that we can issue error messages from
other routines.
3) Check errno in several places and print it out so that errors are
easier to track down.
I don't really expect any of these to fix the current failures I'm
seeing, but I'm hopeful they'll at least let me debug them.

Remove the sysroot restriction from building GCDAProfiling.c.
...
We really need the C standard library to be available to implement the
profiling runtime library reasonably, and replicating everything in the
SDKs tree really isn't addressing any problems we have. Notably, all of
the sanitizer runtimes take the same approach, and this isn't a library
which could end up in a bootstrapping problem where the system headers
aren't even available.
This will hopefully prevent subsequent changes which start using various
other bits of C standard library to make things more debuggable.
