I ran into the same issue attempting to compile from source on
a fresh Ubuntu 16.10/Yakkety host:

Linking C executable bcc-lua
/usr/bin/ld: libluajit-5.1.a(ljamalg.o): relocation R_X86_64_32S
    against `.rodata' can not be used when making a shared object;
    recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output

Build succeeded after patch was applied.
