>Environment:
Linux/Alpha, libc 2.1.2
>Description:
When doing a make bootstrap on my Linux/Alpha installation the
jc1 build fails with a number of missing symbols from the iconv library
(see below).  I think the issue might be that older libc's don't have
iconv in, but have an external iconv library.
