Subject: [PATCH] Do not probe to find main data root start if dl_iterate_phdr
exists
Issue #432 (bdwgc).
This avoids invocation of GC_find_limit to get GC_data_start value in
case of GC_register_data_segments is not called.
* misc.c [SEARCH_FOR_DATA_START] (GC_init): Call
GC_init_linux_data_start() only if GC_REGISTER_MAIN_STATIC_DATA();
move GC_init_linux_data_start() call down (to be close but precede
GC_dirty_init call); add comment.
