gcc-cross-initial: Stage self sufficient fixed limits.h
currently gcc installs a limits.h which references to another limits.h which it expects from target sysroot and that header in target sysroot will come from eglibc. So we need to break this catch-22 and hence we install a self sufficient limits.h which is then happy when referenced and doesnt complain about missing limits.h from target sysroot. This is mostly used when eglibc-initial configure is run Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Saul Wold <sgw@linux.intel.com>
