glibc: Help compile with -Os

Browse Source 
When we modify to use -Os
-Werror doesnt go well with it, glibc needs to be
cleaned up for that but until then lets disable -Werror
when using -Os

Also updates the options group patch to work better with -Os.

(From OE-Core rev: 98e1dc574ef3be668d6a42232ad030d1af93c49f)
