I've a project that must use subdir-objects, because of filename clashes
in subdirectories (non-recursive build).
AM_INIT_AUTOMAKE([-Wall -Werror foreign subdir-objects])
I just have
lib_LTLIBRARIES = libfoo.la
check_PROGRAMS = ${TESTSUITE_TESTS} ${TESTSUITE_XFAIL_TESTS}
but quite a lot of files.
The generated Makefile contains a target "mostlyclean-compile" which has
about 1500 lines that look like
-rm -f src/foo/foo.$(OBJEXT)
-rm -f src/foo/foo.lo
...
Of course it takes ages to say "make clean". About 10 sec.
Wouldn't it be faster if there were just one call to rm or at least
block the number of arguments to rm so that the maximal argument lenght
is not exceeded?
Any idea how I can speed that up?
