Building crosstool-ng on CentOS-7

Crosstool-ng is a project that simplifies building of c/c++ toolchains for many hosts/targets.

For this particular project vendor only provided cygwin build, but I had to run the compiler on linux.

As toolchain was build using crosstool-ng-1.13.1, I simply check-outed that version of crosstool-ng with appropriate configuration and built it.
