Pull request description:

  While using `sed` can be handy to use for a quick-fix, these instances accumulate, and can become unmaintainable. Not only that, but using sed isn't necessarily robust and it can fail silently. Most of our usage is also missing any documentation explaining why something is being done, when it should be updated/removed etc.

  Rather than relying on sed going forward, where possible, I've converted our sed usage into patches. These are easier to maintain, contain documentation, and should fail loudly when they don't apply.

  The remaining sed usage, (1 in miniupnpc, the rest in qt), are non-trivial to remove, as they are using build-time variables, or some input from the environment.

  This also steals 2 related commits out of #19716.

  Related to #16838.

    re-ACK 3de365e4f15ddaaf6bdb5b3c31529156617d2835, only `drop_lrelease_dependency.patch` updated. Travis makes ARM build without errors now.
  theuni:
    ACK 3de365e4f15ddaaf6bdb5b3c31529156617d2835.

+Date:   Tue Aug 25 14:34:53 2020 +0800
+
+    Remove rule that causes inadvertant header regeneration
+
+    Otherwise the makefile will needlessly attempt to re-generate the
+    headers with gperf. This can be dropped once the upstream build is fixed.
+
+    See #10851.

+    Don't use wingenminiupnpcstrings when generating miniupnpcstrings.h
+
+    The wingenminiupnpcstrings tool is used on Windows to generate version
+    information. This information is irrelevant for us, and trying to use
+    wingenminiupnpcstrings would cause builds to fail, so just don't use it.
+
+    We should be able to drop this once we are using 2.1 or later. See
+    upstream commit: 9663c55c61408fdcc39a82987d2243f816b22932.

+
+    Disable threading to fix non-determinism
+
+    A bug in the file parser can cause dependencies to be calculated
+    differently based on which files have already been parsed. This is more
+    likely to occur on systems with more CPUs.
+
+    Just disable threading for now. There is no noticable slowdown.
+

+
+    Fix backwards compatibility with older Freetype versions at runtime
+
+    A few years ago, libfreetype introduced FT_Get_Font_Format() as an alias
+    for FT_Get_X11_Font_Format(), but FT_Get_X11_Font_Format() was kept for abi
+    backwards-compatibility.
+
+    Qt 5.9 introduced a call to FT_Get_Font_Format(). Replace it with FT_Get_X11_Font_Format()
+    in order to remain compatibile with older freetype, which is still used by e.g. Ubuntu Trusty.
+
+    See #14348.

+    Remove needless linking against libstdc++
+
+    This is broken for a number of reasons, including:
+    - g++ understands "static-libstdc++ -lstdc++" to mean "link against
+      whatever libstdc++ exists, probably shared", which in itself is buggy.
+    - another stdlib (libc++ for example) may be in use
+
+    See #11981.
