sim: use -Werror when probing for supported warning flags
When building with clang, we get: error: unknown warning option '-Wmissing-parameter-type' [-Werror,-Wunknown-warning-option] This is because clang only warns by default when encountering an unknown warning option, and the probe for supported warning flags is done without -Werror. All flags are therefore accepted by configure, but then it breaks when actually compiling a source file with -Werror. This is equivalent to this commit in gdb: 3e019bdc20eb81b91ab5bc774386201b874c0bac gdb: Use -Werror when checking for (un)supported warning flags We then see some other compilation errors when building with clang and -Werror, they can be dealt with later.
