LLD 13 and GNU ld 2.37 support -z start-stop-gc which allows garbage collection of C identifier name sections despite the __start_/__stop_ references. Simply set the retain attribute so that GCC 11 (if configure-time binutils is 2.36 or newer)/Clang 13 will set the SHF_GNU_RETAIN section attribute to prevent garbage collection. Without the patch, there are linker errors like the following with -z start-stop-gc. ``` ld: error: undefined symbol: __start_SYSTEMD_BUS_ERROR_MAP >>> referenced by bus-error.c:93 (../src/libsystemd/sd-bus/bus-error.c:93) >>> sd-bus_bus-error.c.o:(bus_error_name_to_errno) in archive src/libsystemd/libsystemd_static.a ```
