Why? For one, libgcc's unwinder makes use of `dl_iterate_phdr`. Also, libgabi++ (the home grown C++ RT we use for stlport) uses `dlopen` for liblog when reporting fatal errors. The LLVM unwinder which is used by libc++ also uses libdl. Requiring a dependency on libdl seems less objectionable than requiring one on liblog. We could always change libgabi++ to use syslog instead, but that will only reach logcat for newer devices (possibly L+, definitely M+). Requiring libdl seems like the best option here, especially given that libgcc needs it anyway. Change-Id: I4acfaf38145c39fc15a76fbb282a46786e5322f1
