build/test problems with latest git code for openwrt

[karlp]

This used to build without any help, but it's less happy now...

pkerror.o: could not read symbols: Bad value

Also, the makefile tries to execute tests now, which is somewhat problematic for the cross compile environment

[karlp]

Further, I've done the normal fixups of trying "TARGET_CFLAGS+=$(FPIC)" and += -fPIC directly, with no effect :(

[karlp]

Nevermind, wasn't "clean" enough. I've fixed the openwrt makefile to properly add the right fpic stuff now, and it's building.

The tests are still being built, and then it attempts to run them, which will never work, but that's a different ticket I think
