So I don't know what I have :(.
That indeed suggests you have an armhf system. I really don't get why
it's installing an ARMEL compiler. Please file a bug with Raspbian
about that.
You can bootstrap an armhf 3.0 compiler on an armel system, but it's a
bit tricky:
1) install the armel compiler (you already did that
2) build FPC with OPT="-dFPC_ARMHF" FPCMAKEOPT="-dNO_THREADING"
This last parameter removes the libc dependency from fpmake, so it
won't need the _init and _fini symbols. It does not remove threading
support from the RTL itself, so that's fine.
This way, FPC 3.0 should build successfully, and you should end up
with an FPC 3.0 ARMHF compiler. You can verify it by running
"./fpcsrc/compiler/ppcarm -l nonexisting.pp" afterwards and checking
that it says it targets ARMHF.
If that is the case, install it in a subdirectory of your home
directory (make ... install INSTALL_PREFIX=$HOME/somedir), create a
symbolic link from $HOME/somedir/bin/ppcarm to
$HOME/somedir/lib/fpc/3.0/ppcarm, add $HOME/somedir/bin to the front
of your path, and finally add the following lines to ~/.fpc.cfg
#ifdef VER3_0
-Fu/home/pi/somedir/lib/fpc/$fpcversion/units/$fpctarget/*
-Fu/home/pi/somedir/lib/fpc/$fpcversion/units/$fpctarget/rtl
#endif
That should enable you to use both "fpc" and "ppcarm" to compile
programs using this newly built FPC 3.0.

Seems it compiles but still complains about linking.
