This is a temporary workaround for some of the ASLTS tests failing to compile
due to acpica commit 73ddb40da6c4afdfe587 as described in...

  https://bugs.acpica.org/show_bug.cgi?id=1112

With regard to stdout and stderr, upstream wants to hide all errors reported by
the iASL compiler when the tests are compiled. And instead indicate their
occurrance through the errors encountered when the tests are run. The iASL
errors are written to tests/aslts/tmp/aml/<version>-<bit>/error.txt. But that
only works if one is running interactively and can access the tmp directory.

So this patch writes to stderr the iASL compiler error info that could normally
be found in compile.txt (also located in the tmp directory). It is not the
detailed error info, but it shows the number of errors encountered for the
named test.
