bdrewery 99c769b1d7 FAST_DEPEND: Rework how guessed dependencies are handled. 
Rather than depend on .depend not existing, check the actual
.depend.OBJ file that will be used for that object.  If it doesn't
exist then use the guessed dependencies.

FAST_DEPEND may never have a .depend file.  Not having one means all of the
previous logic would over-depend all object files on all headers which is not
what we wanted.  It also means that if a .depend is generated before a build
is done for _EXTRADEPEND (such as for PROG or LIB) then all of these
dependencies would not be used since the .depend wasn't generated from mkdep
and the real .depend.* files are not generated until the build.

# alternative directory which is called "sysroot", so during buildworld binaries
# won't be linked against the running system libraries but against the ones of
# the current source tree. ${_LDSCRIPTROOT} behavior is twisted because of
# the location where we store them:
# - 64 bits libs are located under sysroot, so ${_LDSCRIPTROOT} must be empty
# because ld(1) will manage to find them from sysroot;
# - 32 bits shims are not, so ${_LDSCRIPTROOT} is used to specify their full
# path, outside of sysroot.
# Note that ld(1) scripts are generated both during buildworld and
# installworld; in the later case ${_LDSCRIPTROOT} must be obviously empty
# because on the target system, libraries are meant to be looked up from /.
