This setting must have been changed unintentionally by my PR #1214 (probably leftover from unrelated tests)

f81815e48a Fix CMake cross-compiling 
Without specifying thread count, NUM_THREADS would not be defined and CMake would fail.
This is because core count cannot be determined when cross-compiling.

2359c7c1a9 Use .p2align instead of .align for portability 
The OSX assembler apparently mishandles the argument to decimal .align, leading to a significant loss of performance 
as observed in #730, #901 and most recently #1470

e7366a4161 Restore the remaining utests (#1462) 
* Restore the remaining utests

* Try fork test on Cygwin and Linux only, it hangs on at least ARMv8/Android as well

* Use generic sswap/dswap kernels for NEHALEM 32bit to fix fault found by the restored swap utest

* Disable zdotu test for MS cl to work around runtime error -1073741819 on AppVeyor for now
(probably coding error in the initialization of the complex numbers or wrong choice of zdotu API)

3cda1ce50a Revert insiduous suppression of the -fopenmp flag in the LAPACK subtree 
This was added in #1046 citing a problem with mingw, but in effect it quietly reduces thread safety on all non-Windows platforms (while -fopenmp is already disabled for Windows builds through the toplevel Makefile.system). Removing the filter fixes #1425
