Introduce blasabs macro and use it to switch between abs and labs for INTERFACE64

fabs -> fabsl

Fixes two calls that were using `fabs` on a `long double` argument rather than `fabsl`, which looks like it is doing an unintentional truncation to `double` precision.

Set EXPORT_NAME to match OpenBLASConfig.cmake

Haiku supporting patches

Fix #1705 where we incorrectly calculate page locations.

Since we now use an allocation size that isn't a multiple of PAGESIZE, finding
the pages for run_bench wasn't terminating properly.  Now we detect if we've
found enough pages for the allocation and terminate the loop.

Do not treat WIndows UWB builds as cross-compiling

Work around utest failures in the MIPS64 SICORTEX target

Fix wrong redefinitions of snprintf for older MSVC

_snprintf_s takes an additional (size) argument, so is no direct replacement.
(Note that this code is currently unused - the two instances of snprintf here are within ifdef blocks that are not compiled for MSVC)

MS _snprintf_s takes an additional argument for the size of the buffer, so is not a direct replacement (utest/ctest.h from which I copied was wrong)
