glibc: Drop --with-headers in pass 1

Browse Source 
I cannot see why this is ever needed.  The default is "the compiler
default" which should be correct as the compiler has been configured
--with-sysroot.  And the explanation for this switch is just repeating a
common misunderstanding.  In fact glibc **never** attempts to figure out
what features the kernel has from the headers.  Instead it depends on
the kernel-features.h files in the source tree and the --with-kernel
value to determine the kernel features that it can rely on.
