The sdl libpth autodetection gets confused in case a host
version is present. Overwrite libpth autodection for the
target build dependent on BR2_PACKAGE_LIBPTHSEM_COMPAT and
use pth-config from staging directory.
Fixes [1]:
checking for pthreads... no
checking for pth-config... /usr/bin/pth-config
checking pth... yes
[...]
./src/SDL.c:33:17: fatal error: pth.h: No such file or directory
#include <pth.h>

Changes v2 -> v3:
- simplify libpth enable logic, check on BR2_PACKAGE_LIBPTHSEM_COMPAT is enough
(suggested by Baruch Siach)
Changes v1 -> v2:
- add SDL_DEPENDENCIES += libpthsem (suggested by Baruch Siach)
- fix libpth enable logic, needs BR2_PACKAGE_LIBPTHSEM and BR2_PACKAGE_LIBPTHSEM_COMPAT
- overwrite ac_cv_path_PTH_CONFIG to use the right pth-config from
staging dir
