Linux: Add AC_CHECK_LINUX_OPERATION configure macro

Linux: Add AC_CHECK_LINUX_OPERATION configure macro

Add a new macro to check the signature of a particular
operation against a provided typed argument list.
One of the arguments is an arbitrary label that is used
to construct the pre-processor define name.  This will
allow for testing of different forms for the same
operation.

This can be used to replace many of the remaining odd
checks in src/cf/linux_test4.m4.
