[opus] Problems building on Raspberry Pi

[Samuel Bearg]

Hello,

I'm following the directions that 'make check' gave me: to e-mail you log
files.

I'm attempting to build opus on a raspberry pi zero w, which I think has
more or less the original hardware as an original raspberry pi + WiFi.

I'm running a clean install of the latest version of raspbian lite.  Note
that lite has no gui, but also has less packages in general, so it might be
missing something important for building opus.

I tried building opus twice.  Well, it seemed like I succeeded in building
opus twice, but both times the 'make check' tests failed.

Time one I downloaded the tar.gz for 1.1.4.

./configure gave the following output:

------------------------------------------------------------------------
  opus 1.1.4:  Automatic configuration OK.

    Compiler support:

      C99 var arrays: ................ yes
      C99 lrintf: .................... yes
      Use alloca: .................... no (using var arrays)

    General configuration:

      Floating point support: ........ yes
      Fast float approximations: ..... no
      Fixed point debugging: ......... no
      Inline Assembly Optimizations: . No inline ASM for your
platform, please send patches
      External Assembly Optimizations:
      Intrinsics Optimizations.......: ARM (NEON)
      Run-time CPU detection: ........ ARM (NEON Intrinsics)
      Custom modes: .................. no
      Assertion checking: ............ no
      Fuzzing: ....................... no
      Ambisonics support: .............no

      API documentation: ............. yes
      Extra programs: ................ yes
------------------------------------------------------------------------

It appeared to build ok, but 'make check' failed.  The log is attached
as gittest-suite.log

I then cloned the git repository and built from that.  I had to
install git, autoconf, and libtools with apt-get.

I ran both autogen.sh and ./configure with the --enable-fixed-point
flag.  I wasn't sure which one took that argument.

./configure gave the following output.  Once again it seemed to build
ok, but 'make check' failed.  I've attached that as gittest-suite.log

------------------------------------------------------------------------
  opus 1.2-alpha2-38-g43db562:  Automatic configuration OK.

arrays) General configuration:
