Sorry, I don't understand what you mean by that. The break executable only
returns 42 with the working lib.so, it doesn't have to be recompiled.

FTR, this issue does not happen with gold:

# gcc -fuse-ld=gold -fPIC -shared -Wl,--dynamic-list,lib.dynlist -o lib.so
lib.i && readelf --dyn-syms -r lib.so | grep value
000000001fe0  000800000006 R_X86_64_GLOB_DAT 0000000000002014 value + 0
     8: 0000000000002014     4 OBJECT  GLOBAL DEFAULT   24 value
# LD_LIBRARY_PATH=$PWD ./break; echo $?
