The prctl(2) wrapper provided by glibc uses a variadic argument list.
This means that the arguments *must* have the right type (and more
importantly, the right width). To avoid the user having to cast these
constants, provide them with the appropriate width, that of a long.
Having the width of a long is sufficient, and we don't need UL. Let's
reserve that suffix for bit fields, which need to be unsigned to avoid
easily triggering undefined (or implementation-defined) behavior.

The prctl(2) wrapper provided by glibc uses a variadic argument list.
This means that the arguments *must* have the right type (and more
importantly, the right width). To avoid the user having to cast these
constants, provide them with the appropriate width, that of a long.
These are bit fields, and bitwise operations are dangerous on signed
integers, so let's make sure they are unsigned.
