+Subject: [PATCH basu] 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
