This is not an eabi arm debian image, so TCC_ARM_EABI has not been defined. If it was, there would be a /lib/ld-linux.so.3 instead of /lib/ld-linux.so.2. /proc/cpuinfo mentiones VFP floating point support, so TCC_ARM_VFP is defined. But looking at the code generated by gcc, it should not be defined as libc will return values in FPA registers. There also is an issue with double constants having their halves swapped when this is defined incorrectly.
