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