Original bug was reported against gcc-8.1.0. Apologies for the confusion.

gcc-8.2.0 has the same problem. With workaround it manages to build and install
asan libraries:

  /usr/lib/gcc/mips-unknown-linux-gnu/8.2.0/include/sanitizer/asan_interface.h
  /usr/lib/gcc/mips-unknown-linux-gnu/8.2.0/plugin/include/asan.h
  /usr/lib/gcc/mips-unknown-linux-gnu/8.2.0/libasan.a
  /usr/lib/gcc/mips-unknown-linux-gnu/8.2.0/libasan.so
  /usr/lib/gcc/mips-unknown-linux-gnu/8.2.0/libasan.so.5
  /usr/lib/gcc/mips-unknown-linux-gnu/8.2.0/libasan.so.5.0.0
  /usr/lib/gcc/mips-unknown-linux-gnu/8.2.0/libasan_preinit.o

I'm a bit confused by lack of sanitizer support.

I guess you mean that  libsanitizer/configure.tgt has no mips entry and should
fail ./configure or silently skip sanitizer build/install.
