novox/hq issue 161. A repeated flag is not a merged one. The Go command takes the last -ldflags and drops the first, so passing the toolchain's flags and then the system stamp as a second one produced a binary that knew its system and had lost -s -w: 12.2MB against 8.5MB, with its debug info intact.

My own comment in the previous change said the linker "accepts and merges" them. It does not, and I found out by reading the file the build produced rather than by reading the comment again.

Linker flags are now the toolchain's own list, composed into one flag with the stamp. A test refuses a compile line that carries -ldflags itself, because that is what makes two.

make check: only the pre-existing failure.
