Add the ability to GCC_NEED_DECLARATION{S} for looking in arbitrary
header files when searching for function declarations. Use this
functionality to check for getrlimit/setrlimit.
* aclocal.m4 (GCC_NEED_DECLARATION): Accept an optional second
argument, which is typically preprocessor code used to draw in
additional header files when looking for a function declaration.
(GCC_NEED_DECLARATIONS): Likewise.
* configure.in (GCC_NEED_DECLARATIONS): Add checks for getrlimit
and setrlimit, search for them in sys/resource.h.
* acconfig.h: Add stubs for NEED_DECLARATION_GETRLIMIT and
NEED_DECLARATION_SETRLIMIT.
* system.h: Prototype getrlimit/setrlimit if necessary.
