The "hack" is good in a sense that if that check fails in any case
the test_subtest_known_broken is not executed and we get FAIL instead of
BROKEN.
The subshell is unneeded:

	ldd notmuch | grep -q gmime-2.6 && test_subtest_known_broken

does the trick (potentially less forks)... ok now I have to test ;)

haha:
 $ rm xfoo.* xbar.*
 
 $ strace -ff -o xfoo sh -c '(ldd /bin/ls | grep -q libc) && echo foo'
 foo
 $ ls xfoo.*
 xfoo.14277  xfoo.14279  xfoo.14281  xfoo.14283  xfoo.14285
 xfoo.14278  xfoo.14280  xfoo.14282  xfoo.14284

 $ strace -ff -o xbar sh -c 'ldd /bin/ls | grep -q libc && echo foo'
 foo
 $ ls xbar.*
 xbar.14292  xbar.14294  xbar.14296  xbar.14298
 xbar.14293  xbar.14295  xbar.14297  xbar.14299
