    newlib: hoist crt0 install up another dir
    
    Commit dd23de27c8e45513ad276f503a0036c3bc4e487b ("newlib: libc: install
    CRT0 straight out of subdir") got rid of the libc/sys/ intermediate for
    copying the file up, but the top-level newlib/ dir was still expecting
    a libc/crt0.o to exist so it could install.  Update that to also look
    for the crt0 file directly under libc/ like we already do for crt1.
