[PATCH] libitm testsuite fixes

[Cesar Philippidis]

Here is a patch from our backlog that addresses a libitm issue where 
setting ENABLE_LTO=1 in site.exp causes the following error with dejagnu:

ERROR: (DejaGnu) proc "libitm_target_compile linker_plugin19344.c 
linker_plugin19344.exe executable {{additional_flags=-flto 
-fuse-linker-plugin}}" does not exist.

This problem usually does not occur since the default site.exp does not
contain ENABLE_LTO=1. This patch has been tested both with and without
our custom site.exp.

Is this OK for trunk? If so, please check it in since I do not have commit
rights.
