With Microblaze Gcc version < 8.x the build hangs due to gcc bug
85180: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180. The bug
shows up when building opus with optimization but not when building
with -O0. To work around this, if BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y we
force using -O0.

We want to use SPDX identifier for license string as much as possible.
SPDX short identifier for BSD-3c is BSD-3-Clause.
This change is done using following command.

The ARM assembly code in opus uses full ARM instructions, which won't
work on Thumb-2 only platforms such as ARMv7-M, so we disable the
assembly code in such situations.

These flags are already defined in pkg-autotools.mk.
There is no need to have them twice.

The default of choosing the fixed-point implementation if
the target hardware does not have floating-point unit is not
always the best choice. Modern ARM hardware has floating
point support but most likely the fixed-point implementation
in Opus will still perform better. In particular if your CPU
supports the NEON extension.
This commit allows to select the fixed-point implementation
manually and sets the default based on the availability of
a floating-point unit.
