configure: Detect linker's NO_CROSSREFS_TO() support

NO_CROSSREFS_TO() was first introduced in binutils 2.27.
It is used to have the linker report errors when symbols
from a list of sections refer to a specified section,
which is useful for verifying that normal code does not
refer to INIT_ATTR code.

Note this doesn't actually start using NO_CROSSREFS_TO()
for builds -- that will have to wait until the toolchain
upgrade when we'll have a new enough binutils -- it just
detects support for the feature so it can be conditionally
enabled in linker scripts.
