On systems with more than 64 cpus, blas_quickdivide will sometimes return zero which creates bogus workloads when used for the stride calculation. This then leads to threads spinning incessantly waiting for a status change that never happens, as seen in #1497.
This patch also fixes several data races that were found by helgrind and/or tsan while debugging the issue.

* prebuild.cmake: Put quotes around path names that may contain whitespace
(Copied from alexkaratakis' PR #1295)
* kernel/CMakeLists.txt: Fix common_lapack header inclusion and DYNAMIC_ARCH generation of ?neg_tcopy and ?laswp_ncopy files
* lapack/CMakeLists.txt: Use correct template for ?laswp_(plus,minus) functions

If OpenBLAS is built using add_subdirectory(OpenBlas) as part of another project
then the paths set by CMAKE_XXX_DIR are relative to the parent project
and not the OpenBLAS project.

Seperated mips and mips64 files.
Configurations support for mips 32 bit.

Instead of generating separate object files for each permutation of
defines for a source file, GenerateNamedObjects now writes an entirely
new source file and inserts the defines as #define c statements.

This solves a problem I ran into with ar.exe where it was refusing to
link objects that had the same filename despite having different paths.

This will generate obj files for SINGLE/DOUBLE/COMPLEX/DOUBLE COMPLEX.

MSVC doesn't inmplement C99, so can't use the inline keyword. __inline
appears to work in MSVC and GCC.

It sets DBLAS_OBJS directly to save a bunch of list appending in the
CMakeLists.txt files.

This function caused the failure of ERKALE serial test.
I replaced it with LAPACK source code.

I used a smaller threshold since the stack size is 1MB on windows.
