optee-client: refresh patch applied upstream

PR has been closed upstream with modifications to originally submitted
patch. Later implementation implied more modification, which are not
compatible with current version, therefore accepted patch has been
backported to this fork.

 Subject: [PATCH] flags: do not override CFLAGS from host
 
 Some build systems set CFLAGS in environment before the build, but they
 got overridden by CFLAGS immediate assignment operator.
 
-Replace immediate assignment with append directive, so the former
-definition of CFLAGS gets properly expanded.
+Replace immediate assignment with append directive and use override
+directive, so the former definition of CFLAGS gets passed either from
+command line or via environment is completely expanded (see [1] for
+detailed explanation of override directive and variable append).
 
-Upstream-Status: Submitted [https://github.com/OP-TEE/optee_client/pull/211]
+Link: [1] https://www.gnu.org/software/make/manual/html_node/Override-Directive.html

+Upstream-Status: Backport [https://github.com/OP-TEE/optee_client/pull/211]
