-lib:
-       libasan is disabled currently (haven't tried yet)
-
-new stuff:

-
-+           doc/gcov-tool.1

-
-arch/feature list.  anything not here has been switched already:
-
-tools:         does build.sh tools work?

-[2] - -O2 and -Os kernels hang, -O1 SIR reset
-       -- may be a SMP issue; ultra10 works, ultra45 SMP does not
-               -- try sb2000 (particularly with UP kernel.  u45 UP is shitty.)
-[3] - MKCOMPAT=no enabled currently, infact OABI seems to be broken.  the docs say it was only deprecated, but the options make broken stuff.
-[5] - sh3eb tries to use sh specific atomic config which doesn't work, has hand edited mknative output
-[6] - crtbeginS.o builds incorrectly with GCC 5.3 and -O2.  a hack for -O1 has been added.
-[8] - sgimips64 release build fails, mdsetimage'd gz'd kernels don't get built?
-[10] - needs to be re-merged with GCC 5.3 versions of these not-merged-to-mainline-gcc ports.
-[13] - builds tested:
-       - m68k: mvm68k amiga atari
-       - earm : shark evbarm*
-       - mipseb: sgimips evbmips
-       - mipsel: evbmips
-       - mips64eb: sgimips[fail] evbmips
-       - mips64el: evbmips
-[14] - machines tested:
-       - sparc ss20 (OK)
-       - sparc64 ultra45 (FAIL), ultra10 (OK), sb2000 (OK UP, FAIL SMP.)
-       - powerpc pegasosII (OK)
-       - alpha UP1000 (OK)
-       - arm shark (OK)
-       - evbmips gxemul MALTA
-               - had to implement some MIPS32 in gxemul to make this work
-       - pmax gxemul (OK)
-       - sgimips O2 (OK kernel -- but my O2 is not stable)
-       - i386/amd64 (OK)
-       - hppa (OK)
-       - amiga (OK)
-[15] - vax -- switched to GCC 5.3 already as it is less broken
-       - ssh is broken, was broken with 4.8
-       - there are too many -O0's we added because of mis-handled rtl
-       - the eh_frame stuff is probably busted, but it never worked?
-[16] - kernels tested:
-       - m68k: amiga
