#
# ${_LDSCRIPTROOT} is the directory prefix that will be used when generating
# ld(1) scripts.  The crosstools' ld is configured to lookup libraries in an
# 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 /.
