Node.jsをコンパイルしたときにgccが古い！と指摘された。
wikiを見ると最新版は9.2なんだそうな。
ps. 今は、gcc-10.2.0 らしい。
インストしてみることにした。

１．ReadyRAS-212の/rootは容量が少ない（3.7GB）ので
エラーが出るから、/home/xxxxx(5.5TB：HDD容量に依る)で作成する。

../../gcc/lto/Make-lang.in:81: recipe for target 'lto1' failed２．–prefix=/usr/localで、楽にシェルで使えるしようとすると
make install で失敗してしまった。
make uninstallが使えなくなっていたので、そのせいかもしれない。
–prefix=/usr/local/gcc-9.2.0にする。
----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/lib/gcc/armv7l-unknown-linux-gnueabi/9.2.0/plugin
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use ：ｑ, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

※CentOSならグループはwheel。
※Ubuntuは、usemod -G のパラメータの順序が逆だそうで非常に危険。
