"llvm-ar xv lib.a" from LLVM 8 doesn't print extracted object file
names. The effect of "v" is not formally specified either.
Use "llvm-ar t" to get archive member names.

Use current build directory as base for temporary directories,
so that all build files are isolated there.

clang archiver tool is llvm-ar on Windows and ar on other platforms.
MinGW always uses ar. Replace shell script (Unix-only) that calls ar
with a Python script (OS-independent) that calls an appropriate archiver
tool selected at configuration time. Move the logic not to generate
empty sources into pmdinfogen.
