UPDATE: I may have found the solution to this issue; googling libasan and libpthread yielded a link to gnu-user.h from a different repo which led me to hunt down the 4.8.0 version of the same file, which included two additional defines: /* Additional libraries needed by -static-libasan. */ #undef STATIC_LIBASAN_LIBS #define STATIC_LIBASAN_LIBS "-ldl -lpthread" /* Additional libraries needed by -static-libtsan. */ #undef STATIC_LIBTSAN_LIBS #define STATIC_LIBTSAN_LIBS "-ldl -lpthread" I've added these to the end of the 4.9.2 gnu-user.h and am currently re-running make after running make clean in the builddir/gcc directory.
