samples/bpf: Fix tracex5 to work with MIPS syscalls.
There are two problems: 1) In MIPS the __NR_* macros expand to an expression, this causes the sections of the object file to be named like: . . . [ 5] kprobe/(5000 + 1) PROGBITS 0000000000000000 000160 ... [ 6] kprobe/(5000 + 0) PROGBITS 0000000000000000 000258 ... [ 7] kprobe/(5000 + 9) PROGBITS 0000000000000000 000348 ... . . . The fix here is to use the "asm_offsets" trick to evaluate the macros in the C compiler and generate a header file with a usable form of the macros. 2) MIPS syscall numbers start at 5000, so we need a bigger map to hold the sub-programs.
