openwrt-packages/gforth/Makefile
David Kühling 915bd10172 Make Gforth's built-in assembler/disassembler work on non-mips architectures. 
Added comments about how builds for 64-bit targets may currently fail.

## Note for tuning: In theory you could strip down the resulting packages size
## a lot, if you removed gforth and gforth-fast executables and only included
## the (somewhat slower) gforth-itc and/or gforth-ditc interpreter binary that
## rely on classic indirect threaded code without the (code-bloating) engine
## optimizations.
##
## Also we could create multiple packages here 'gforth-minimal' and 'gforth'?

## Compilation is pretty manual to only build the parts we need. By default

## work with a cross-compile environment.
##
## Todo: we currently always build the -ll-reg version of the engine. On
## 64-bit architectures this might not work? Damn it, why is the check for
## 'long long' in the Gforth Makefile, not the configure script?
## Todo: develop a clean upstream patch to configure/Makefile
