0000492: make install fails with GCC internal error on Fedora 31

Description

The 'make install' step fails for 20.01-beta-2020-01-12 on Fedora 31 with the following message when attempting to build the library in the asm_fast.gc.debug.stseg grade. The GCC version is 9.2.1.

Notes
~0001065 wangp (developer) 2020-01-13 19:54	I previously reported it here: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91430

~0001066 juliensf (administrator) 2020-01-13 20:05	Do you know if there is a workaround we can use for it?

~0001067 wangp (developer) 2020-01-13 20:52	Unfortunately, no.

~0001068 juliensf (administrator) 2020-01-15 14:42	Also, occurs with Alpine Linux 3.11 (GCC 9.2). I think we will just need to force GCC to use -O0 in debug grades with GCC 9.1 and 9.2. (The bug only seems to be triggered in debug grades.)

~0001069 juliensf (administrator) 2020-01-18 22:23	We now force the use of gcc -O0 in debug grades with GCC 9. (Confirmed that installation of the source distribution works with both Fedora 31 and Alpine Linux 3.11 out of the box.)
