# Note [slotting support]
# -----------------------
# Gentoo's layout for binutils files is non-standard as Gentoo
# supports slotted installation for binutils. Many tools
# still expect binutils to reside in known locations.
# binutils-config package restores symlinks into known locations,
# like:
# /usr/bin/${CTARGET}-<tool>
# /usr/bin/${CHOST}/${CTARGET}/lib/ldscrips
# /usr/include/
#
# Note [tooldir hack for ldscripts]
# ---------------------------------
# Build system does not allow ./configure to tweak every location
# we need for slotting binutils hence all the shuffling in
# src_install(). This note is about SCRIPTDIR define handling.
#
# SCRIPTDIR defines 'ldscripts/' directory location. SCRIPTDIR value
# is set at build-time in ld/Makefile.am as: 'scriptdir = $(tooldir)/lib'
# and hardcoded as -DSCRIPTDIR='"$(scriptdir)"' at compile time.
# Thus we can't just move files around after compilation finished.
#
# Our goal is the following:
# - at build-time set scriptdir to point to symlinked location:
# ${TOOLPATH}: /usr/${CHOST} (or /usr/${CHOST}/${CTARGET} for cross-case)
# - at install-time set scriptdir to point to slotted location:
# ${LIBPATH}: /usr/$(get_libdir)/binutils/${CTARGET}/${PV}
