so you type in 'make all' and then see nothing on the screen?

all: chk_makej
        @${OMAKE}  PETSC_ARCH=${PETSC_ARCH}  PETSC_DIR=${PETSC_DIR} chk_petscdir chk_upgrade | tee ${PETSC_ARCH}/conf/make.log

The only thing I can think off is chk_upgrade perhaps misconfigured
network is affecting it. [if the behavior is reproduceable - perhaps
we can narrow it down by invoking these commands one at a time].

If x11 includes/libs are not found - then petsc is configured without X11.

The configure.log above confirms that it did not detect X11. [so none
of the X11 stuff was enabled].

Even if X11 was enabled - 'make test' does not run any X11 related tests.

If some make target caused hang for both 'make all' and 'make test' -
then running the examples manually might confirm this. [and then
invoking the steps in 'make test' one at a time might narrow down to
the location of the hang].
