[oe] do_compile of gcc-cross-sdk-4.5 fails with -mfloat-abi=hard

[Julian Pietron]

 Hallo,

 I encountered a problem on bitbaking meta-toolchain for a Cortex A8 CPU 
 with hardfp enabled. I'm using a modified cm-t35 machine which enables 
 ARM_FP_MODE="hardfp" to enforce using the hardware FPU. Up to 
 compilation of gcc-cross-sdk-4.5 everything is fine, but the build 
 process fails on linking some files to libgcc_s.so.1.tmp, please see 
 attached log.do_compile for more information.
 Currently I'm trying to build with ARM_FP_MODE="softfp" to see whether 
 the problem persists, but I don't think so as it seems to be related to 
 the VFP instructions. My guess is that somewhere in the build process 
 the TARGET_CC_ARCH flags are not applied where they should have been 
 applied.

 Thanks for your help,
 Julian
