[Buildroot] [PATCH] package/brotli: add missing TARGET_CFLAGS on Bug 68485

[Giulio Benetti]

When building with Bug 68485 only '-O0' flag is used loosing
TARGET_CFLAGS. Add BROTLI_CFLAGS variable initialized with TARGET_FLAGS
and if Bug 68485 is present append '-O0' to it. Then pass it to
CMAKE_C_FLAGS.
