--- Comment #1 from Jack Howarth <howarth at nitro dot med.uc.edu> 2011-06-17 00:09:42 UTC ---
I don't believe r169822 is the cause but I see what is happening. During the
build two libgcj.spec files are generated. One in
x86_64-apple-darwin11.0.0/libjava, which properly substitutes LDLIBICONV, and a
second in x86_64-apple-darwin11.0.0/i386/libjava which produces an empty string
for LDLIBICONV. A quick examination of the Makefile's in each directory shows
why.

[MacPro:darwin_objdir/x86_64-apple-darwin11.0.0/libjava] root# grep LDLIBICONV
*
Makefile:LDLIBICONV =  -L/sw/lib -liconv 
config.log:LDLIBICONV=' -L/sw/lib -liconv '
config.status:S["LDLIBICONV"]=" -L/sw/lib -liconv "

[[MacPro:x86_64-apple-darwin11.0.0/i386/libjava] root# grep LDLIBICONV *
Makefile:LDLIBICONV =   
config.log:LDLIBICONV='  '
config.status:S["LDLIBICONV"]="  "

It appears that the multi lib build doesn't pass along the value for LDLIBICONV
into the multi lib and that the installed gcj.spec must be coming out of
x86_64-apple-darwin11.0.0/i386/libjava.
