Patch from Christophe Massiot:
Hello,
When using uClibc to compile the modutils for a MIPS target, the linker
outputs an "undefined symbol: _flush_cache". After some digging, it's
a syscall only available on the MIPS architecture, and the _flush_cache
symbol is in the GNU libc.
Attached patch defines it in uClibc as well. I'm not sure if I made it
the right way, though, but it works for me.
