Thomas Petazzoni 95f9a5c3df uboot-tools: fix static linking with OpenSSL
Add a patch to U-Boot to use pkg-config to get the OpenSSL link flags
when pkg-config is available. This allows to make sure that static
linking works properly. The patch requires adding $(TARGET_MAKE_ENV)
so that the Buildroot provided pkg-config is used instead of the host
one.

The U-Boot patch has been submitted upstream.

Subject: [PATCH] tools: use pkg-config when available to get SSL flags
Instead of hardcoding -lssl -lcrypto as the flags needed to build
mkimage with FIT signature enabled, use pkg-config when
available. This allows to properly support cases where static linking
is used, which requires linking with -lz, since OpenSSL uses zlib
internally.
We gracefully fallback on the previous behavior of hardcoding -lssl
-lcrypto if pkg-config is not available or fails with an error.
