Both GNU and LLVM linkers de facto accept `-zPARAM`, and Go sometimes
does it. Inconsistently: there are more uses of `-z PARAM` than
`-zPARAM`:
$ git grep -E -- '-Wl,-z[^,]' master | wc -l
4
$ git grep -E -- '-Wl,-z,' master | wc -l
7
However, not adding a space between `-z` and the param is not
documented:
llvm-13:
$ man ld.lld-13 | grep -E -A1 -w -- "^ +-z"
-z option
Linker option extensions.
gnu ld:
$ man ld | grep -E -A1 -w -- "^ +-z"
-z keyword
The recognized keywords are:
--
-z defs
Report unresolved symbol references from regular object files. This is done even if the linker is creating a non-symbolic
--
-z muldefs
Normally when a symbol is defined multiple times, the linker will report a fatal error. These options allow multiple definitions
--
-z
--imagic
... and thus should be avoided.
`zig cc`, when used as the C compiler (`CC="zig cc" go build ...`), will
bark, because `zig cc` accepts only `-z PARAM`, as documented.
Closes ziglang/zig#11669
