[kaffe] CVS kaffe (dalibor): Fixed make check failures on x86_64-linux

Hi,

> Fixed make check failures on x86_64-linux

The most important part was to get PROM_f defined correctly, which this 
patch doesn't address, hence the bug still remains. ;-)

I have a patch to get rid of PROM_f and use if (PROMOTE_jfloat2jdouble) 
to select the right dest member, but that wouldn't be consistent with 
usage of PROMOTE_jint2jlong. Doing so for the latter would be 
obfuscating the code IMHO as there are a lot of references to PROM_i to 
replace as well.

Really, using regular #if THING is OK, or I could remove 
PROMOTE_jfloat2jdouble definitions to 0 in config/* but the comments in 
support.c would be stale.

Bye,
Gwenolé.
