I did build from today's git. After setting libsystemd to off
OPTION_DEFAULT_OFF([libsystemd],[don't compile with libsystemd support])
the build was successful: all three built executables: temacs, bootstrap-emacs,
emacs works fine.

Forcing usage of SYSTEM_MALLOC fails with bootstrap-emacs:
Dumping under the name emacs
45802 pure bytes used
mv -f emacs bootstrap-emacs
make -C ../lisp compile-first EMACS="../src/bootstrap-emacs"

Will try the release 25.1 tarball next: Last time I built from an upstream
tarball it did succeed the first time and failed the second.
