The patch tool will apply patches by default with "fuzz", which is where if the
hunk context isn't present but what is there is close enough, it will force the
patch in.
Whilst this is useful when there's just whitespace changes, when applied to
source it is possible for a patch applied with fuzz to produce broken code which
still compiles (see #10450). This is obviously bad.
We'd like to eventually have do_patch() rejecting any fuzz on these grounds. For
that to be realistic the existing patches with fuzz need to be rebased and
reviewed.

libtool tries to guess the --tag value based on CC/CXX environment
variables and the compile commandline generated by makefiles. This
heuristics however fails when we construct CC variables in OE
and add security flags to it, especially -fPIE -pie which are added
by external compilers e.g. clang particularly. It fails because
libtool removed PIE flags from compiler cmdline intelligently
if it figures out that its building a library, which means that
the CC variable passed from cmdline does not match with the compiler
cmdline constructed by libtool and we end up with errors like
| arm-bec-linux-musleabi-libtool: compile: unable to infer tagged configuration
| arm-bec-linux-musleabi-libtool: error: specify a tag with '--tag'
This works with internal gcc toolchain because we configure gcc for
PIE when hardening is selected and dont pass -fPIE -pie options explicitly
but this is not an option for clang, and some external gcc toolchains
using older gcc
This patch adds the --tag option to help libtool set correct tags
in packages where it cant get it right via its heuristics

While code elsewhere checks for
MIPS_INSTRUCTION_SET == mips16e in order to decide how
to compile, hence the typo doesn't affect behaviour, the
intention was to set it to 'mips', as is done everywhere
else. Fixing the typo also helps to avoid confusion.

libffi contains hand-written assembly which is not compatible with
the MIPS16e mode.
