REVISION SUMMARY
kstars appends '-Wl,-z,nodump' to the linker flags, which is not supported
by lld>=7 (previous versions just discareded unkonwn flags).
Add an ecm module to check whether a linker flag is supported.
Usage:
```
include(ECMCheckLinkerFlags)
[...]
# Check for nodump support
SET(NODUMP_FLAGS "-Wl,-z,nodump")
ecm_check_linker_flags("${NODUMP_FLAGS}" NODUMP_SUPPORTED)
if (NODUMP_SUPPORTED)
SET(SEC_LINK_FLAGS "${SEC_LINK_FLAGS} ${NODUMP_FLAGS}")
endif ()
```
