tools/nolibc: Fix position of -lgcc in the documented example 

The documentation header in the nolibc.h file provides an example command
line, but it places the -lgcc argument before the source files, which
can fail with libgcc.a (e.g. on ARM when uidiv is needed). This commit
therefore moves the -lgcc to the end of the command line, hopefully
before this example leaks into makefiles.  This is a port of nolibc's
upstream commit b5e282089223 to the Linux kernel.

* A simple static executable may be built this way :
* $ gcc -fno-asynchronous-unwind-tables -fno-ident -s -Os -nostdlib \
* -static -include nolibc.h -lgcc -o hello hello.c
* -static -include nolibc.h -o hello hello.c -lgcc

* A very useful calling convention table may be found here :
