Correct. These .LCx symbols only cover .rodata.* sections. Any other
local symbols:

[konrad@x230 x86]$ readelf --symbols prelink.o |grep bad_hypercall
 8946: 0000000000145549     0 NOTYPE  LOCAL  DEFAULT    1 compat_bad_hypercall
 8967: 0000000000145c79     0 NOTYPE  LOCAL  DEFAULT    1 bad_hypercall

don't get dropped and do show up in the binary (nm --defined finds them).

While .LC matches the type:
 9147: 00000000000008c0     0 NOTYPE  LOCAL  DEFAULT   33 .LC5

They are in four other sections:
konrad@x230 x86]$ readelf --symbols prelink.o |grep LC | awk '{print
$7}' | sort | uniq
