include alloca.h if available.
On LynxOS, alloca is defined in allocal.h. This fixes one warning that
occurs when building GDBserver for LynxOS.
gdb/gdbserver/ChangeLog:
* configure.ac: Add configure check for alloca.
* configure, config.in: Regenerate.
* server.h: Include alloca.h if it exists.
* gdbreplay.c: Include alloca.h if it exists.
