Aurelien thanks for taking care and resheduling the build. Unfortunately
this did not solve the problem. But setting the following variables
solves the virtual memory issue for me on the mipsel porterbox (eller):

export DEB_CFLAGS_MAINT_APPEND= --param ggc-min-expand=10 -O1
export DEB_CXXFLAGS_MAINT_APPEND= --param ggc-min-expand=10 -O1
export DEB_CFLAGS_MAINT_STRIP= -O2
export DEB_CXXFLAGS_MAINT_STRIP= -O2

But unfortunately the build fails at another point. See the log below.
I'm not sure how to fix this. If I understand it right these atomic
operations are just not supported on mipsel[1]. Or is there a way to make
them work?
