Hello,

I tried to build Newlib b095628ecff1831b250f34d3b6b5787b3f247d63 and it 
fails in make install with:

[PATCH/committed] newlib: hoist crt0 install up another dir

[Mike Frysinger]

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.

Thanks, this worked. I would have never found out this fix myself.
