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