As mentioned several times before, the standard FPC 2.6.4 does not
support the Linux distributions for the Raspberry Pi. You get the linker
error because FPC has been compiled for ARM EABI (aka "armel") and is
looking for the symbols in the ARM EABI startup code (which is probably
not installed on your system), while the Raspberry Pi uses ARM EABIHF.

The solution is to use the FPC 2.6.4 from the package repository of your
Raspberry Pi Linux distribution, or to compile FPC 3.x instead of FPC
2.6.4 (with OPT=-dFPC_ARMHF while building FPC).
