Subject: [PATCH] Use AC_COMPILE instead of AC_RUN to check for execinfo.h
This way enables cross compiling, since we don't need to run anything
during the configure script.

Subject: [PATCH] Modify configure to prevent unnecessary kqueue checks
By only running the TORRENT_CHECK_KQUEUE_SOCKET_ONLY check if kqueue support
is already detected, we increase the number of platforms that we can
cross compile on.
Otherwise, the cross compilation fails due to TORRENT_CHECK_KQUEUE_SOCKET_ONLY
using AC_RUN_IFELSE, which fails during cross compilation.
