>From these lines:

build-gnulib/import/stdlib.h:41:20: fatal error: /usr/lib/gcc/mips-linux-gnu/4.9/include/ctddef.h: No such file or directory
  #include <stddef.h>
                     ^

gcc lists the correct source include (stddef.h), but then complains
about not finding ctddef.h, so it looks like memory flipped somewhere
between (or while) reading the include file name and then trying to
access the include file.
