Unfortunately, this doesn't work.
I see
PASS: gdc.dg/gcov1.d   execution test
ERROR: (DejaGnu) proc "run-gcov conditions { --conditions gcov1.d }" does not exist.
The error code is TCL LOOKUP COMMAND run-gcov
The info on the error is:
invalid command name "run-gcov"
    while executing
"::tcl_unknown run-gcov conditions { --conditions gcov1.d }"
    ("uplevel" body line 1)
    invoked from within
"uplevel 1 ::tcl_unknown $args"
ERROR: gdc.dg/gcov1.d  : error executing dg-final: invalid command name "run-gcov"
both on x86_64-linux and i686-linux.
The problem is that the test hasn't been added to a new directory, but
to a directory already covered by a different *.exp file - dg.exp.
Now, usually either one has a test directory like gcc.misc-tests where
there are many *.exp files but each *.exp file globs for its own tests,
or there is one *.exp per directory and covers everything in there.
By having both dg.exp and gcov.exp in the same directory with dg.exp
covering all *.d files in there and gcov gcov*.d in there, the gcov*.d
tests are tested twice, once using the dg.exp driver and once using gcov.exp
driver.  With the latter, they do work properly, with the former they don't
because gcov.exp lib file isn't loaded and so run-gcov isn't available.

The following patch fixes that similarly how g++.dg/modules/modules.exp,
gcc.target/s390/s390.exp or gcc.target/i386/i386.exp deal with that,
by pruning some tests based on glob patterns from the list.
