Hi Masahiro,
With v5.11-rc1 and commit("1e860048c53ee gcc-plugins: simplify GCC
plugin-dev capability test"), I get this error for my arm
socfpga_defconfig build. I have been building the kernel the same way
for many years now. Do you know what I might be doing wrong?

Hi! Thanks for the report. Other folks have also encountered this,
and it appears to be a problem with distro packaging of the gcc plugin
development packages. You'll need to install the GNU multiprecision
libraries ("gmp-devel" on most rpm-based systems, "libgmp-dev" on most
debian systems)[1].
Hopefully that'll work!

Thanks, that worked! I also had to install libmpc-dev as well.
