freepascal on armhf again
I decided to take another look at the freepascal armhf issue and decided
that the first step would be to build freepascal with vfp enabled but
still the softfloat ABI then once that was working.
(note: i'm currently working on upstream fpc svn, if/when I get things
working reasonablly on armhf I will look into backporting to the version
in debian)
Unfortunately when I try to build freepascal with vfp enabled
make all 'OPT=-dFPC_ARMEL -CfVFPV3'
I get assembler errors.

Any idea what exactly these errors mean (e.g. do any processors support
these instructions and if so which ones), what is causing this (e.g. why
is freepascal generating these instructions) and what if anything I can
do about it?
