[patch/testsuite] gdb.base/auxv.c: add #include for gcc HEAD

[Michael Chastain]

This patch adds "#include <stdlib.h>" to gdb.base/auxv.c, so that it
compiles with gcc HEAD 20040804, which gives a warning if "abort" is used
without a prototype.

Tested on native i686-pc-linux-gnu, gcc 2.95.3 3.3.4 3.4.1
HEAD-20040804, dwarf-2 and stabs+.

I am committing this now.  Plus a lot more of these little one-liners,
preceded by copyright addition patches for the files that need them.
