lib/string.c: Use freestanding environment
...
gcc can transform the loop in a naive implementation of memset/memcpy
etc into a call to the function itself. This optimization is enabled by
-ftree-loop-distribute-patterns.
This has been the case for a while, but gcc-10.x enables this option at
-O2 rather than -O3 as in previous versions.
Add -ffreestanding, which implicitly disables this optimization with
gcc. It is unclear whether clang performs such optimizations, but
hopefully it will also not do so in a freestanding environment.
