Siarhei Siamashka eb2d4570d3 sbc: ARMv6 optimized version of analysis filter for SBC encoder 
The optimized filter gets enabled when the code is compiled
with -mcpu=/-march options set to target the processors which
support ARMv6 instructions. This code is also disabled when
NEON is used (which is a lot better alternative). For additional
safety ARM EABI is required and thumb mode should not be used.

Benchmarks from ARM11:

Compilation and installation
============================

In order to compile Bluetooth utilities you need following software packages:
	- Linux Bluetooth protocol stack (BlueZ)
	- GCC compiler
	- D-Bus library
	- GLib library
	- USB library (optional)
	- Lexical Analyzer (flex, lex)
	- YACC (yacc, bison, byacc)

To configure run:
	./configure --prefix=/usr --mandir=/usr/share/man \
		--sysconfdir=/etc --localstatedir=/var --libexecdir=/lib

Configure automatically searches for all required components and packages.

To compile and install run:
	make && make install
