# objcopy: FLAGS
# Use the specified program to analyze the assembler or linker
# output file, and pass it FLAGS, in addition to the output name.
+# Note that they are run with LC_ALL=C in the environment to give
+# consistent sorting of symbols.
#
# source: SOURCE [FLAGS]

#
# target: TARGET
# Only run the test for TARGET. This may occur more than once; the
