Hello again,

sorry to reopen this issue, but one part was skipped. It was just now found out, because it doesn't cause build issues, but only runtime issues (GCC fails to build binaries):
/usr/local/bin/ld: /usr/local/lib/gcc10/libgcc_s.so: undefined reference to `.__udivmodti4'
/usr/local/bin/ld: /usr/local/lib/gcc10/libgcc_s.so: undefined reference to `.__ctzdi2'
/usr/local/bin/ld: /usr/local/lib/gcc10/libgcc_s.so: undefined reference to `.__parityti2'
/usr/local/bin/ld: /usr/local/lib/gcc10/libgcc_s.so: undefined reference to `.__enable_execute_stack'

Could you commit the following patch:
