[PATCH 0/6] systemtap set of --sysroot option handling fixes

[Victor Kamensky <kamensky@cisco.com>]

Hi Folks,

Here is set of fixes for SystemTap --sysroot option handling.

Please look at individual patches decsription for issues observed and fixed.

If commit messages are too details and big for SystemTap project
guidelines feel free to trim them. Commit message structured in such
way that text after "Here are steps how to reproduce the issue." could
be removed if needed.

I did not run full SystemTap regression with --sysroot option since SystemTap
DejaGnu testsuites are not friendly to remote execution mode. I did run
regular 'make installcheck' on the same baseline with and without changes
and made sure that results are identical.

If you would like to try stap in cross compiled environment with --sysroot
option I've set up openembedded-core repository where these changes are
integrated and since openembedded-core support virtual qemu based target
for different CPU types stap with --sysroot option could be tested.

Setup instructions are here:
