GNSS-SDR v0.0.8 accepted into Debian testing

GNSS-SDR v0.0.8 has been accepted as a software package in Debian testing and Ubuntu 16.10.

This package fixes building when using the new releases of gnuradio 3.7.10 and libvolk1.3, thus closing bug #828034.

The package also closes bug #828040, resulting in a expanded list of processor architectures in which GNSS-SDR can be built, now including:

• i386: Intel x86 instruction set (32-bit microprocessors).
• amd64: also known as x86-64, the 64-bit version of the x86 instruction set, originally created by AMD and implemented by AMD, Intel, VIA and others.
• armel: ARM embedded ABI, supported on ARM v4t and higher.
• armhf: ARM hard float, ARMv7 + VFP3-D16 floating-point hardware extension + Thumb-2 instruction set and above.
• arm64: ARM 64 bits or ARMv8.
• mips: MIPS architecture (big-endian, such as those manufactured by SGI).
• mipsel: MIPS architecture (little-endian, such as Loongson 3).
• mips64el: 64-bit version of MIPS architecture.
• powerpc: the RISC 32-bit microprocessor architecture developed by IBM, Motorola (now Freescale) and Apple.
• ppc64: 64-bit big-endian PowerPC architecture.
• ppc64el: 64-bit little-endian PowerPC architecture.
• s390x: IBM System z architecture for mainframe computers.

This is an improvement in Portability.
