[U-Boot] HOSTCC version

[Andy Pont <andy@embeddedsw.co.uk>]

Hello,

What version of host gcc is needed for building the tools such as
mkimage.exe?  My embedded Linux development environment is Cygwin (1.3.22)
based and includes gcc 3.4.4 which gives compiler errors for versions of
U-Boot 1.3.3 and later.

And so it goes on!  If I remove mkimage from the BIN_FILES line of
tools/Makefile then the rest builds OK.

Thanks in advance,

A.
