[PATCH v2 1/4] engine.pl: Fix a recent breakage of the buildsystem generator

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

Commit ade2ca0c (Do not try to remove directories when removing
old links, 27-10-2009) added an expression to a 'test' using an
'-o' or connective. This resulted in the buildsystem generator
mistaking a conditional 'rm' for a linker command. In order to
fix the breakage, we filter out all 'test' commands before then
attempting to identify the commands of interest.

Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk>

Changes from v1, in response to comments from Pete Harlan and
Sebastian Schuberth:

    - remove second (useless) regex from condition in filter code
    - remove the commented out version of the original filter code
    - re-worded commit message to reflect the above changes

ATB,
Ramsay Jones
