<c:make/> fails on Solaris

[webkontakt@…]

For what reason ever, <c:make/> does not perform well on Solaris, but returns "Success":

[ERROR   ] make: Warning: Ignoring DistributedMake -c option
[INFO    ] MAKEFLAGS value:
[ERROR   ] bash: all-recursive: command not found
[INFO    ]    Building config.h because it is out of date relative to stamp-h1
[INFO    ]   Building all because it is out of date relative to config.h
[INFO    ] all-recursive
[INFO    ] *** Error code 127 (ignored)

Funny enough, replacing the recipe by <sh:exec executable="make"/"> results in a real build success.
