Added all symbols to assembler (not just FPU_PRESENT=1). Removed unused c ...

compiler argument.

Misc fixes for LPC4088/LPC4088DM: ...

- Resetting in LPCXpresso IDE did not reset the LCD controller which
  sometimes could cause strange behaviour
- The ROM_LAT bit in the MATRIXARB register must be set in order to
  prevent a HardFault when debugging
- The change of compiler in LPCXpresso IDE to ARM launchpad GCC5 was
  causing build errors due to multiply defined timeval symbol.
- The exporters for LPCXpresso IDE did not set the FPU_PRESENT define
  for assembler, only for c/c++. This caused very strange behaviour
  in the RTOS code (e.g. timeouts no longer working, context switches
  failing etc.)

[export] Add no rtti flag to exporters

[LPC4088] Corrected FPU setting in LPCXpresso project file

[LPC4088] Switch to 'hard' FP ABI on GCC ...

This is consistent with the armcc compilation options.

Fix LPC4088 codered exporter ...

Use softfp instead of hardfp for code generation, in order to make linking
with the mbed SDK (generated with softfp) possible.

Added: Export to uVision and Code Red toolchains
