Kbuild: link against libc only for newlib Right now we are building minimal libc as an archive (lib.a) and do not need to link against -lc -lm in that case. Link against libc/libm only when using an external libc. Change-Id: I1af0eaf5c059bd5f0c8c16cda28114c6dc10b156 Signed-off-by: Anas Nashif <anas.nashif@intel.com>

build: Make QEMU_BIN_PATH optional QEMU_BIN_PATH is frequently set to pick up qemu binaries from "obvious" places such as /usr/bin or /usr/local/bin. Neither of these values will be correct for all users and both directories would typically be found in the user's PATH. Much better to make QEMU_BIN_PATH optional and picking up qemu via PATH instead. Tested with ZEPHYR_GCC_VARIANT={zephyr|xtools}.
