It doesn't seem to be a disk space issue, but rather a virtual memory
issue. It's limited to 3GB on armhf, and 2GB on mipsel.

For mipsel, you might want to try to add --param ggc-min-expand=20 to
the CFLAGS/CXXFLAGS to lower the memory consumption in GCC. For armhf,
there is probably similar kind of options for ld.gold.
