318# A list of tool executables to preserve for each multilib ABI.
319# The listed executables will be renamed to ${CHOST}-${basename},
320# and the native variant will be symlinked to the generic name.
321#
322# This variable has to be a bash array. Paths shall be relative to
323# installation root (${ED}), and name regular files or symbolic
324# links to regular files. Recursive wrapping is not supported.
325#
326# If symbolic link is passed, both symlink path and symlink target
327# will be changed. As a result, the symlink target is expected
328# to be wrapped as well (either by listing in MULTILIB_CHOST_TOOLS
329# or externally).
330#
331# Please note that tool wrapping is *discouraged*. It is preferred to
332# install pkg-config files for each ABI, and require reverse
333# dependencies to use that.
334#
335# Packages that search for tools properly (e.g. using AC_PATH_TOOL
336# macro) will find the wrapper executables automatically. Other packages
337# will need explicit override of tool paths.
