textrels from bundle.o due to missing CFLAGS
The Makefile builds bundle.o without $(CFLAGS), leading to textrels if the whole program is being built as PIE. Depending on the target, textrels may not be supported at all, resulting in failure of the program to run. It looks like timestamp.o and build.o may also be affected. This was reported by a LEDE user building for ARM with musl libc. Simply adding $(CFLAGS) to the $(pCC) command lines that are currently missing it should fix the problem.
