To make sure the problem isn't shell dependent, I ran a bootstrap on
alpha-dec-osf5.1b with CONFIG_SHELL set to bash: the same problem occured
as with /bin/ksh.

In the alpha-dec-osf5.1b build mentioned above, I find in
alpha-dec-osf5.1b/libjava/config.cache:
ac_cv_env_CPPFLAGS_value='-O2 -g -O2 -mieee'
i.e. the extra space occurs. In config.status, there is
with options \"'--cache-file=./config.cache' '--host=alpha-dec-osf5.1b'

I.e. the extra space is present here, too.
In libltdl/config.log, I find
$ /vol/gnu/src/gcc/gcc-dist/libjava/libltdl/configure --prefix=/vol/gcc

Here, the extra space is gone.
