sigrok-cross-linux: Add file for simple Linux (cross-)compiles.

This script can be adjusted to build the sigrok components for various
Linux-based targets via various cross-toolchains.

Per default it will do native builds though, i.e. it can also be used
just as a simple "I don't want to type that much" script to clone,
build, and install (e.g. in $HOME/sr) all sigrok components in one go.

+README
+-------------------------------------------------------------------------------
+
+This is a small script for cross-compiling sigrok and its dependencies
+for Linux systems (various architectures / cross-toolchains).
+
+It can also be used for native builds (this is actually the default) when
+no cross-compiler setup is specified (see the top of the script).
+
+
+Status
+------
+
+Working.
+
+
+Requirements
+------------
+
+ - bash
+ - gcc
+ - make
+ - cmake
+ - git
+ - wget
+ - unzip
+ - pkg-config (>= 0.22)
+ - sdcc (needed for building the fx2lafw firmware)
+
+
+Building
+--------
+
+ $ ./sigrok-cross-linux
+
+Per default it will install the (cross-)compiled packages in:
+
+ $HOME/sr
+
+Please edit the script if you want to change any settings.
