Description of problem:

I am aware that cross-{binutils,gcc} are limited to be useful only for bootloader/kernel compilation as there is no userspace support in packages.

But they can also be used for userspace compilation when sysroot with libraries/headers is created.

Version-Release number of selected component (if applicable):

2.23.88.0.1-2

How reproducible:

always

Steps to Reproduce:
1. grab aarch64 system image
2. populate it with glibc-devel
3. mount at /mnt
4. aarch64-linux-gnu-gcc helloworld.c --sysroot /mnt -o hello-aarch64

Actual results:

"linker is not configured for sysroots"

Expected results:

links and gives proper binary

Additional info:

Same is needed for cross-gcc and will be reported.
