# PRELINK - Prelink a list of files
# This is useful when files were compiled with fvisibility=hidden.
# Any symbol which was not explicitly made global is invisible outside the
# prelinked file.
#
# Example: $(call PRELINK, prelink-file, "file1 file2 file3 ...")
#
# Note: The fileN strings may not contain spaces or characters that may be
# interpreted strangely by the shell
#
# Depends on these settings defined in board-specific Make.defs file
# installed at $(TOPDIR)/Make.defs:
#
# LD - The command to invoke the linker (includes any options)
# OBJCOPY - The command to invoke the object cop (includes any options)
#
# Depends on this settings defined in board-specific defconfig file installed
# at $(TOPDIR)/.config:
#
# CONFIG_WINDOWS_NATIVE - Defined for a Windows native build
