GCC Version 10.1.0 failing on compilation of a BUILT IN function call in LFS "Illegal Instruction Internal Compiler Error"

My build is frozen this is figured out. I'm using jhalfs to get started but the issue is most certainly gcc-10.1.0

I get the following error in the make log. The error outwardly says this a gcc thing... but.

`/sources/gcc-10.1.0/build/./gcc/xgcc -B/sources/gcc-10.1.0/build/./gcc/ -B/usr/x86_64-pc-linux-gnu/bin/ -B/usr/x86_64-pc-linux-gnu/lib/ -isystem /usr/x86_64-pc-linux-gnu/include -isystem /usr/x86_64-pc-linux-gnu/sys-include    -g -O2 -O2  -g -O2 -DIN_GCC    -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-error=format-diag -Wstrict-prototypes -Wmissing-prototypes -Wno-error=format-diag -Wold-style-definition  -isystem ./include  -fpic -mlong-double-80 -DUSE_ELF_SYMVER  -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector  -fpic -mlong-double-80 -DUSE_ELF_SYMVER  -I. -I. -I../.././gcc -I../../../libgcc -I../../../libgcc/. -I../../../libgcc/../gcc -I../../../libgcc/../include -I../../../libgcc/config/libbid -DENABLE_DECIMAL_BID_FORMAT -DHAVE_CC_TLS  -DUSE_TLS -o _mulxc3.o -MT _mulxc3.o -MD -MP -MF _mulxc3.dep -DL_mulxc3 -c ../../../libgcc/libgcc2.c -fvisibility=hidden -DHIDE_EXPORTS

make[2]: Leaving directory '/sources/gcc-10.1.0/build'
make[1]: *** [Makefile:961: all] Error 2
make[1]: Leaving directory '/sources/gcc-10.1.0/build'`

is there any workaround or solution or do I have to downgrade ? What precisely happened that 10.1.0 was released buggy IF that is the case.

Some other similar but far from the same issues were solved by arch changes but i'm using the correct compiler and make system for my arch.
