Hmph.  I'm also running it on the /home filesystem, and I used
these settings:

export CC=3D"ccache gcc -mips32r2"
export CFLAGS=3D"-O2 -funwind-tables"
export LDFLAGS=3D"-rdynamic"

./configure --enable-debug --enable-cassert --with-systemd --enable-nls --=
with-icu --enable-tap-tests --with-system-tzdata=3D/usr/share/zoneinfo

plus uninteresting stuff like --prefix.  Now maybe some of these
other options affect this, but I'd be pretty surprised if so.
So I'm at a loss why it behaves differently for you.
