Problem Description:
Currently "libnuma-dev" library is NOT mandatory for Linux. A user
can compile MySQL on Linux without "libnuma-dev".

The above test will fail wherever the libnuma-dev library is
not installed. It was recently seen on Developer's testing machines
(eg. rpl Hudson machines).

Fix:
A skip file is introduced which provide a means for users who do not
want to explicitly install the libnuma-dev libraries before running
the tests.
