Enable checking for syscalls during configure and compiling against them.
2011-09-21 Andrew John Hughes <ahughes@redhat.com>
* Makefile.am:
(ICEDTEA_ENV): Set COMPILE_AGAINST_SYSCALLS
if USE_SYSCALL_COMPILATION is set.
* acinclude.m4:
(IT_CHECK_FOR_SYSCALLS): Add --enable-compile-against-syscalls
which checks for various syscalls (epolling, extended attributes,
*at).
* configure.ac: Call IT_CHECK_FOR_SYSCALLS.
