Message:

configure: Fix check_exec_crash for ICL support

Change the check_exec_crash test to use a function pointer instead of
simply calling the function. The EBP availability test will crash when
compiled with ICL likely due to compiler optimization shenanigans.

Originally the check_exec_crash code was moved out of main to fix a
problem with gcc's treatment of non-leaf main on x86_32. Libav already
moved the code out of main but the addition of the function pointer will
prevent any inlining which fixes the remaining problem.

A function pointer is used since it is compiler agnostic (as opposed to
say attribute ((noinline)) which would only work with gcc compatible
compilers).
