Every other developer of FPC will tell you the same: The only supported 
version for compiling a development (2.7.1) or fixes (2.6.3) version is 
either the last release (2.6.2) or a development/fixes version of the 
same revision and nothing else.

2.7.1 definitely is a development version and it sometimes happens that 
things will break in a way that a older revision is no longer able to 
build a newer one. We do not check for compatibility with older 
revisions and the only way we guarantee that works is a compilation with 
2.6.2.

The softfloat 2.6.2 compiler should be able to compile a hard float one 
and as far as I've understood the softfloat discussion it should also 
work on hardfloat systems. Otherwise you could compile a hardfloat 
compiler on a Debian system (using a 2.6.2 as starting compiler), move 
that to your odroid U2 and build the compiler (of the same revision!) 
with that (the compiler does not use libc or any other library so you 
can freely move it between Linux systems).
