tools: zstd: add patch fixing wrong generated .pc with lib-mt
The current .pc generated by make build system for zstd is wrong and always assume a single-threaded library is used. This wasn't the case for the meson build system that used his own logic to generate the pkg-config file. Add a patch to fix this by introducing install-mt-pc make target to generate the correct pkg-config gile. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

Subject: [PATCH] Provide variant pkg-config file for multi-threaded static lib
|
||||
|
||||
Multi-threaded static library require -pthread to correctly link and works.
|
||||
The pkg-config we provide tho only works with dynamic multi-threaded library
|
||||
and won't provide the correct libs and cflags values if lib-mt is used.
|
||||
|
||||
To handle this, introduce a variant of libzstd.pc.in, mt-libzstd.pc.in
|
||||
and intoduce a new make target, install-mt-pc to permit advanced user to
|
||||
install and generate a correct pkg-config file for lib-mt.
|
||||
|
||||
This was notice while migrating from meson to make build system where
|
||||
meson generates a correct .pc file while make doesn't.
