[PATCH RFC 0/3] selftests/nolibc: avoid spurious kernel relinks

[Thomas Weißschuh]

Currently the nolibc testsuite embeds the test executable into a kernel
image with CONFIG_INITRAMFS_SOURCE.
This forces a full kernel relink everytime the test executable is
updated.

This relinking step dominates the test cycle.
It is slower than building and running the test in qemu together.

With a bit of Makefile-shuffling the relinking can be avoided.
