Add "patch" and "yacc" to prerequisites

[sebastianbergmann]

A fresh installation of Fedora 21 does not have patch and yacc installed.

I'm suprised to hear that Fedora does not install patch by default. However yacc should not be required to compile the toolchain as I build flex / bison from sources:

https://github.com/cahirwpz/m68k-amigaos-toolchain/blob/master/bootstrap.sh#L196

Can you verify that the build script picks up flex / bison from m68k-amigaos-toolchain/host/bin directory instead of yacc?

Kind regards Krystian Bacławski

Some part of bootstrap.sh errored out with yacc: command not found. Would have to uninstall yacc and re-run to provide more information.

Here's the relevant output with error when yacc is not available:

Looks like yacc is required to build flex :-)

Thanks Sebastian for reporting the problem.

I'll have a look at it after Revision 2015 demoscene party, somewhere in mid-April.

Have fun @ Revision!
