package/libfastjson: fix build without threads
libfastjson is supposed to use the __sync_*4 atomic intrinsics, but alas
it is not using them because their ./configure decides they are not
available: it uses AC_TRY_RUN to check for them, and the default is to
decide they are not available, because of cross-compilation.
Besides, one of the source files was not including the generated
config.h, so even after fixing ./configure there was still a build
error.
The first patch is a backport from upstream to fix the missing
inclusion.
The second patch is switching AC_TRY_RUN over to AC_LINK_IFELSE, as the
only thing we're interested in is to check for the presence of the
atomic intrisics, and linking is enough for that.
