Add initial XL C compiler flags for safer builds 

This commit adds some default initial C flags for the XL compiler.  The
most important is "-qhalt=e" which causes the compiler to error-out on
non-severe error messages.  This is necessary to get try-compiles to
fail when bad arguments are passed to a function.
