  In your last line:
 make install INSTALL_PREFIX=/usr/lib/fpc/$TARGET_VER

you do not specify any FPC make variable value.

In such cases, the Makefile will look for fpc
binary in the path, probably find it as /usr/bin/fpc
and it will depend on which /usr/bin/fpc it is:

  If this binary is linked to the i386-linux installation,
it will give i386 as default CPU_TARGET and linux as OS_TARGET,
and you will thus use ppc386 executable to recompile everything.

  I suppose this all comes from the fact that the x86_64 Free pascal
was installed before the i386 version, thus overwriting the x86_64 version of fpc binary.

  You can fix your problem simply by adding explicitly
 FPC=$COMPILER
to the make install line.
