Currently the check for EABI/EABIhf toolchains looks for the Tag_ABI_VFP_args attribute in the crt1.o file which gcc adds in an EABIhf toolchain. In uClibc, however, crt1.o is not compiled from c but assembly, so the Tag_ABI_VFP_args attribute is not added in the object file. This causes the EABIhf check in the external toolchain logic to fail for uClibc-based toolchains. Fix by compiling a dummy .c file and trying to link the object against the C library. Since it is impossible to mix EABI and EABIhf code, a mismatch between the buildroot and toolchain ABI settings will be detected during this link step.
