I can build master on FreeBSD HEAD (amd64). Should hybrid_malloc work/be
used on FreeBSD (i386)?

I've tried this patch:

diff --git a/configure.ac b/configure.ac
index 286ca52..098ee52 100644
--- a/configure.ac
+++ b/configure.ac
@@ -2124,7 +2124,7 @@ esac
 
 if test "${system_malloc}" != yes && test "${doug_lea_malloc}" != yes \
    && test "${UNEXEC_OBJ}" = unexelf.o; then
-  hybrid_malloc=yes
+  hybrid_malloc=no
 fi
 
 GMALLOC_OBJ=

Now the build fails later with this error:

  CCLD     temacs
gmalloc.o: In function `calloc':
/mnt/daten/source/emacs/src/gmalloc.c:1801: undefined reference to `gcalloc'
