Subject: BaseTools: Support custom library build for base tools on Linux ARM

This change added the build script to cross compile the base tool
binaries for Linux ARM/AARCH64 systems.

The needed libuuid system library is pulled from source file and rebuilt
to support the corresponding library dependencies. Individual tools'
makefiles are also updated to link the cross compiled library as well.

The EDK2 base tool build script was also updated to support such change.

This was tested functional on Linux ARM host system.
