c952a92e20 testsuite: Move complex tests to their own subdirectory 
It seems a bit silly to isolate them by globbing vs "*complex*"
when we can just as easily put them in their own subdirectory.

b5ade2fb5d testsuite: Detect clang 
Clang doesn't like the -Wno-psabi argument that we want to pass to GCC.
Since clang is detected as GCC via __GNUC__, use ax_cv_c_compiler_vendor.

5d69d57a05 configure: Move target source selection into configure.host 
This eliminates the AM_CONDITIONAL ugliness, which eliminates
just a bit of extra boilerplate for a new target.

At the same time, properly categorize the EXTRA_DIST files
into SOURCES and HEADERS, for the generation of ctags.

9622ede2e2 Fix floating point number comparisons in testsuite/libffi.call/float[123].c. 
Rewrite the checks for approximate equality of floating point return
values to be in the form "fabs(a - b) < EPS" instead of just
"a - b < EPS".

e029c70fa7 Update i386 & armv7 minimum iOS version to 7.0 
iOS 5 (and any below 7.1) is deprecated. Apple doesn't distribute the supporting libraries for this platform anymore as of Xcode 6, so it causes a linker error.

6eec410f15 sparc: Re-add abi compliant structure support 
The original code, removed in the "rewrite" patch, was incorrect for
large structures, and required dynamic allocation of a trampoline on
every ffi_call.

Instead, allocate a 4k entry table of all possible structure returns.
The table is 80k, but is read-only and dynamically paged, which ought
to be better than allocating the trampoline.

This is difficult to test with gcc.  One can only use -O0 at present.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63668.

2b27890ba7 sparc: Rewrite everything 
It's impossible to call between v8 and v9 ABIs, because of the stack bias
in the v9 ABI.  So let's not pretend it's just not implemented yet.  Split
the v9 code out to a separate file.

The register windows prevent ffi_call from setting up the entire stack
frame the assembly, but we needn't make an indirect call back to prep_args.

5d7b544505 sparc: Tidy up symbols 
Assembly to use local labels, .type annotation, hidden annotation.
I do retain the _prefix for the symbols, but given that it wasn't
done consistently across all symbols, I doubt it's actually needed.
