>Description:
	qt4-qmake-4.8.4 installs the file
	$PREFIX/share/qt4/mkspecs/features/unix/gdb_dwarf_index.prf
	which contains the following lines:

    QMAKE_GDB_INDEX += \
      test \$\$(gdb --version | sed -e \'s,[^0-9]\\+\\([0-9]\\)\\.\\([0-9]\\).*,\\1\\2,;q\') -gt 72 && \
      gdb --nx --batch --quiet -ex \'set confirm off\' -ex \"save gdb-index $$QMAKE_GDB_DIR\" -ex quit \'$(TARGET)\'  && \
      test -f $(TARGET).gdb-index && \
      $$QMAKE_OBJCOPY --add-section \'.gdb_index=$(TARGET).gdb-index\' --set-section-flags \'.gdb_index=readonly\' \'$(TARGET)\' \'$
(TARGET)\' && \
      $$QMAKE_DEL_FILE $(TARGET).gdb-index || true

	Unfortunately, the regex is specific to gsed, and when the
	corresponding scriptlet

	test $(gdb --version | sed -e 's,[^0-9]\+\([0-9]\)\.\([0-9]\).*,\1\2,;q') -gt 72

	is run, it fails with the following error:

	test: GNU: unexpected operator

>How-To-Repeat:
	Test the line:
	test $(gdb --version | sed -e 's,[^0-9]\+\([0-9]\)\.\([0-9]\).*,\1\2,;q') -gt 72

	Then compare to:
	test $(gdb --version | gsed -e 's,[^0-9]\+\([0-9]\)\.\([0-9]\).*,\1\2,;q') -gt 72

>Fix:
	Either replace sed by gsed, adding the dependency, or
	translate the regex to our sed.

	Yet better, since the base GDB is older, this part might be
	ommitted?
