Detect usage of GNU libc.

For a header that I have to install (i.e., there is no possibility to
use a config.h file) I need to detect if the libc used is glibc.  How
can I do this?  features.h define __GLIBC__, but are features.h available
in other libc implementations?

The reason for all this is that I want to be able to use the endian
swap functions in byteswap.h, whenever they are available.
