[LTP] [COMMITTED 1/1] numa: Fix numa v2 detection for cross compilation

[Petr Vorel]

Changed to AC_COMPILE_IFELSE as AC_RUN_IFELSE cannot be run while
cross compiling.

AC_RUN_IFELSE was run only if numa headers are installed, that's why our
travis build tests didn't find that.

Bug found by Buildroot project:
http://autobuild.buildroot.net/results/21a/21a6eeddbf5ccffc34c38527d0807305a5eb3917/

I'll also detect this in travis.
