[Lazarus] Cross-compiling to win32 from debian stretch

[kardan]

Hi,

summary: my fpc and ppcross* have different versions, because I can't
build fpc with the installed version. Why does this happen:

~/src/fpc(master)$ make all
Makefile:2918: *** The only supported starting compiler version is
3.0.2. You are trying to build with 3.0.4..  Stop.

$ find /|grep 'fpc*.cfg'
/etc/fpc.cfg
/etc/fpc.cfg.bak
/usr/lib/fpc/3.0.4/ide/text/fp.cfg
/usr/share/fpcsrc/3.0.4/utils/fpcmkcfg/fpccfg.inc
/home/tomboy/src/fpc/utils/fpcmkcfg/fpccfg.inc

$ /home/tomboy/src/fpc# ls -ls /usr/share/fpcsrc/
total 4

0 lrwxrwxrwx 1 root root    1 Nov 27 18:33 3.1.2 -> .

(These version numbers are nonsense, just needed a way to
separate the version from zip (3.1.1) and trunk (3.1.2) before I
dropped the first.)

So it should be found, no?

The term ppu was new to me. I just return from reading [1] and
installed the binutils:
$ sudo apt-get install binutils-mingw-w64 binutils-powerpc-linux-gnu
binutils-powerpc64-linux-gnu

true.

Now it's time to learn from you again.
