Starting with a plain i386 2.6.2 and building trunk on Linux with

make FPC=ppf8 OPT="-dFPC_ARMHF" CPU_TARGET=arm CROSSOPT="-Cparmv7a -CfVFPv3" CROSSBINDIR="/home/jmaebe/diablo/toolchains/armv7-gcc-481-binutils-222-eglibc-217-hard/bin" BINUTILSPREFIX="arm-linux-gnueabi-" all -j 8 FPMAKEOPT="-T 8"

The resulting "ppcarm -i" output:

$ ./ppcarm -i
Free Pascal Compiler version 2.7.1

Compiler Date      : 2014/03/05
Compiler CPU Target: arm

Supported targets:
  Linux for ARMHF
  WinCE for ARM
  GameBoy Advance
  PalmOS
  Nintendo DS
  Embedded
  Symbian OS for ARM
  Darwin for ARM
  Android for ARMEL
...
Supported ABI targets:
  DEFAULT
  EABIHF
...

Similarly, the cross-compiler also shows that it generates ARMHF code. Note that the above procedure is not really advised, and it's better to first build a native trunk compiler and only then a compiler for another architecture with this first one. But it most definitely results in an ARMHF compiler.
