[Octave-bug-tracker] [bug #54182] .o files created by mkoctfile should be removed

[John W. Eaton]

Follow-up Comment #5, bug #54182 (project octave):

The CROSS macro in mkoctfile.in.cc refers to building a cross-compiler aware
version of mkoctfile that can be used to cross compile .oct file for Windows
builds of Octave, not that mkoctfile itself is being cross compiled.

We do use the wrapper and gnulib functions when we are cross-compiling
mkoctfile (to install and run on Windows systems).  That works because we've
already cross-compiled the gnulib and wrapper libraries for Windows.  But when
we are trying to build the cross-compiler aware version of mkoctfile, we can't
use those.  Since there were originally just a few functions we needed, we
simply provided simple versions of them inside mkoctfile.in.cc.

This approach works OK since we are typically building the cross-compiler
aware version of mkoctfile on a modern Linux system that shouldn't need to
have gnulib to fix POSIX portability problems.

I'll fix.
