It's a known failure.  You can see the full log here:

  https://us-east.manta.joyent.com/pkgsrc/public/reports/upstream-trunk/20210117.2254/gcc10-10.2.0nb1/build.log

The error being:

  ../../../../gcc-10.2.0/libsanitizer/sanitizer_common/sanitizer_linux.cpp:903:63: error: 'O_DIRECTORY' was not declared in this scope

Given the heavily threaded nature of the GCC build it can be difficult
to find the actual error as so many other builds will be happening at
the same time.

The fix would be to apply a similar patch to this:

  https://github.com/omniosorg/gcc/commit/7ce599ce25dc0b6d793c6bbedc21d6acdf4587c3#diff-8ae71675698739f1650d88779904f669f3294f69458ae94a693efe5a697f1ed3

Generally on SunOS systems we use the illumos GCC tree, as it has a
large number of patches that have not yet been (or will never be)
upstreamed to mainline GCC.
