| |
From: Mahesh Kumar Kalikot Veetil <mkalikot@codeaurora.org>
Modules with a large number of compilation units may be exceeding AR and LD command argument list. Handle this gracefully by writing the long argument list in a file. The command line options read from file are inserted in place of the original @file option.
The usage is well documented at https://www.gnu.org/software/make/manual/html_node/File-Function.html
