[distcc] Suggestion: m32 option

[Timo Stripf]

Hi,

i'm using distcc to distribute compilation to two machines: One i386 
and one amd64. The i386 is the client machine. This works fine when i 
add the -m32 switch to the CXXFLAGS. So i had the idea that distcc 
could support this via the host list that you can specify an m32 
option on every amd64 host in the host list and distcc automatically 
adds the -m32 switch when compiling on these servers.

e.g.
i386.example.com
amd64.example.com,m32

The benefit would be that you don't have to modify the gcc command 
line parameters when compiling with distcc and that people gets 
informed that this cross compilation is possible.

Best regards
