jhbuild automatically builds modules in parallel by passing '-j' to make, but I'd like to suppress that for certain modules which can't handle parallel builds.  If I specify

 module_makeargs = { 'mymodule' : '-j 1' }

in jhbuildrc, that works fine: jhbuild will build the module with -j 1.  But if in the module's definition in the moduleset file I specify

<autotools id="mymodule" makeargs="-j 1">

jhbuild runs 'make -j 1  -j 5' and the build still runs in parallel.
