o new eabihf (hard float) abi
o vfpv3_d16 variant of VFP (default variant used by EABI assemblers: VFPv3
with only 16 double registers instead of 32) and pass it to GNU as
o make the odd numbered single precision floating point VFP registers
available for explicit allocation for use by the calling convention
* fixed copy/paste error in stdname of S30 register
-> use -dFPC_ARMHF to create an ARM eabi hard float compiler
(mantis #21554)

Mac OS X/iOS version for the compiler code
o such a parameter is not passed, extract the information from the
environment variables MACOSX_DEPLOYMENT_TARGET/IPHONEOS_DEPLOYMENT_TARGET,
like gcc
o if neither the parameter nor the environment variable is used, use preset
default values
o pass on this version setting on to the Darwin linker
o use this setting to determine which version of the startup code (crt1.o
etc) to use, if any (based on information gathered from the GCC sources)
o define a symbol called MAC_OS_X_VERSION_MIN_REQUIRED/
IPHONE_OS_VERSION_MIN_REQUIRED based on this parameter
o for usage information, see

apparently not passing -arch triggers a bug in Xcode 4.2 Lion linker,

Every startup code must now provide an additional entry point called "_dynamic_start" that is set as new the entry point if the program links to a Pascal shared library. Its purpose is to set up an exit hook usually passed via a register, which should be called during program finalization if non-nil.
We use this additional entry point because this register only has meaningful content when there are any compile-time linked shared libraries, otherwise it often contains random garbage. The difference between the _dynamic_start and the original code is minimal; actually in all implementations the _dynamic_start code passes on control to the old startup code, so we use an additional entry point instead of an additional startup file.
Detailed changes and fixes list:
compiler:
always link to the dynamic loader (ld.so) when compiling shared libraries. Fixes crashes in the loader during shared library finalization on some Linuxes
remove additional ENTRY() section in arm linker script
select either _dynamic_start or _start as entry point depending on whether this is a static or dynamic executable
powerpc*:
do not set System.isLibrary in startup code, it will be set during library initialization anyway
trap in case of reaching code locations that should not be reached instead of looping (possibly endlessly)
powerpc:
register atexit() function pointer if supplied to the executable and call it during shutdown
correctly set argc/argv/envp in shared library code and return correctly to the caller after initialization
pass on exitcode in shared library haltproc
use the more recent exit_group system call if available for shutdown
powerpc64
fix .ptrgl stub, do not set the environment register to the value of the GOT entry in the function descriptor
arm
do not set System.isLibrary in startup code, it will be set during library initialization anyway
reload exitcode to pass to shutdown
mips,mipsel,sparc
added stubs to allow correct linking

* converts the embedded information into controller specific records (arm and avr)
* new cpu-specific units for several Stellaris (Fury and Tempest class) targets,
+ STM32F103RB
- old Stellaris unit has been removed

The old linker option to accept object files from all subarchitecture
types no longer works.
+ support for subarchitectures in fcl-res/fpcres
