-lsvl644li: Command not found.

There is a similar problem when making so/spadmin.bin and spadmin.bin in
padmin/source.

The reason for the failure is because the makefiles use a file called
<targetname>.cmd in the misc subdirectory of the output tree.  When two targets
with the same name are built, such as soffice and so/soffice, the same command
file is created: misc/soffice.cmd.

I see two ways to fix this:

1. Add a dependency to one of the conflicting targets on the other target, so
that they get built sequentially.

2. Fix the central makefiles to take the directory of the object file into
account for the .cmd file name, i.e. generate misc/soffice.cmd and
misc/so/soffice.cmd in this example.

Method 1. is more of a quick hack than a proper fix, but is quicker to do and
affects less source files.  Maybe it is the least intrusive fix for 644?  I
think that in the non-short term, method 2. should be implemented.
