5f972324ee Build: Make the NASM autoconf variable persistent 
Previously, if a custom value of this variable was specified when
running configure, then that value would be lost if configure was
automatically re-run (as a result of changes to configure.ac, for
instance.)

As a bonus, the NASM variable is now also listed when running
'configure --help', so it is obvious how to override the default
NASM command.

5f2cbbd039 Fix iOS ARM64 build broken by removal of .arch 
The unnecessary .arch directive was removed from the ARM64 SIMD code
in d70a5c12fc, thus allowing clang's
integrated assembler to assemble the code on Linux systems.  However,
this broke the detection mechanism in acinclude.m4 that tells the build
system whether it needs to use gas-preprocessor.pl.  Since one of the
primary motivators for using gas-preprocessor.pl with ARM64 builds is
the lack of .req/.unreq directives in Apple's implementation of clang,
acinclude.m4 now checks whether .req/.unreq can be properly assembled
and uses gas-preprocessor.pl if not.

Closes #33.

d70a5c12fc Remove unnecessary .arch directive in ARM64 code 
This directive was preventing the code from assembling using the
integrated assembler in clang.

495e43426e Allow for building the MIPS DSPr2 extensions if the host is mips-* as well as mipsel-*. The DSPr2 extensions are little endian, so we still have to check that the compiler defines __MIPSEL__ before enabling them. This paves the way for supporting big-endian MIPS, and in the near term, it allows the SIMD extensions to be built with Sourcery CodeBench.
