tools/nolibc/string: export strlen()nolibc-fixes
As with commit 8d304a374023, "tools/nolibc/string: export memset() and memmove()", gcc -Os without -ffreestanding may fail to compile with: cc -fno-asynchronous-unwind-tables -fno-ident -s -Os -nostdlib -lgcc -static -o test test.c /usr/bin/ld: /tmp/cccIasKL.o: in function `main': test.c:(.text.startup+0x1e): undefined reference to `strlen' collect2: error: ld returned 1 exit status As on the aforementioned commit, this patch adds a section to export this function so compilation works on those cases too.
