common.cpp: In static member function 'static void CTimer::rdtsc(uint64_t&)':
common.cpp:107:56: error: impossible constraint in 'asm' caught my attention.

README.txt says

     make -e os=XXX arch=YYY

XXX: [LINUX(default), BSD, OSX]
YYY: [IA32(default), POWERPC, IA64, AMD64]

Thus it probably needs porting to ARM rather than this being a compiler error.

Yup, this was fixed at version 4.8-2, by restricting the build architectures to i386 and amd64.
