crossdev: set --without-headers by default

In https://sourceware.org/PR24577 we discovered that riscv
can't really install libc headers as it needs a cross-compiler.

Before this change we had the following default build order:
- cross-binutils
- kernel/libc headers
- stage1 gcc
- glibc
- stage2 gcc

After this change it's:
- cross-binutils
- stage1 gcc
- kernel headers
- glibc
- stage2 gcc

Users can still fors headers installation with '--ith-headers' option.
