Running make check-all on android after cross-compiling to it.

[Jeffrey Brusseau]

Ran another test this time I ran the first test manually in bash via a
script I made:

This is the run.bash file:

/data/data/com.spartacusrex.spartacuside/files/build/Release+Asserts/bin/clang

It ran perfectly after exporting the LD_LIBRARY_PATH to libclang:

export
> LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/data/data/com.spartacusrex.spartacuside/files/build/Release+Asserts

So then I tried to recreate the error by changing the $TMPDIR environment
variable and lo and behold it's the exact error you get from the same test.

export TMP=/FOO

make ENABLE_OPTIMIZED=1 check-all

output

Error by clang_getRemappingsFromFileList

Could not create file: /FOO/heaader1.h-30ac2..h
> Could not create file: /FOO/file2.m.in-2c5017.in

So it appears that however clang is actually being run in the test it's not
using the correct environment or the variable is being overruled by
something in the test.
