binman: Document how CROSS_COMPILE, CC, HOSTCC etc. are used in README

Browse Source 
Explain that binman interprets these environment variables in the
"External tools" section to run target/host specific versions of the
tools, and add a new section on how to use CROSS_COMPILE to run the
tests on non-x86 machines.

but the --toolpath option can be used to specify additional search paths to
use. This option can be specified multiple times to add more than one path.
For some compile tools binman will use the versions specified by commonly-used
environment variables like CC and HOSTCC for the C compiler, based on whether
the tool's output will be used for the target or for the host machine. If those
aren't given, it will also try to derive target-specific versions from the
CROSS_COMPILE environment variable during a cross-compilation.

Running tests on non-x86 architectures
--------------------------------------
Binman's tests have been written under the assumption that they'll be run on a
x86-like host and there hasn't been an attempt to make them portable yet.
However, it's possible to run the tests by cross-compiling to x86.
To install an x86 cross-compiler on Debian-type distributions (e.g. Ubuntu):
$ sudo apt-get install gcc-x86-64-linux-gnu
Then, you can run the tests under cross-compilation:
$ CROSS_COMPILE=x86_64-linux-gnu- binman test -T
You can also use gcc-i686-linux-gnu similar to the above.
