Comment # 12 on bug 1091864 from Marcus R�ckert

so the thing that is broken with the cmake version of the %make_jobs macro
(compared to the version in the Qt package)

is 

%make_jobs -C build/something

the params end up after the the %endif of the cmake make_jobs macro

the main difference between the 2 macros is enabling verbose mode and support
for ninja. the first step is already handled by the __builder macro. but the
verbose flag is why we need the %if, so my proposal would be the following
change.

```
# added the %_make_output_sync from %make_build here as it is useful.
%__builder_verbose \
%if "%__builder" == "%__make" \
    %{?_make_output_sync} VERBOSE=1 \\\
%else \
    -v \\\
%endif \
%{nil}

%make_jobs %__builder \\%__builder_verbose %{?_smp_mflags}
```

this makes Fabian's usecase work. now the question is on how do we make this
change in a backwards compatible way. in ideal world we would just move the
whole %make_jobs macro to the rpm macros file but that would require a
maintenance update for rpm and everyone building against :Update.

or we just copy the macro around and have a comment that asks people to keep
the macro in sync between the different places. thoughts?
