Hi,
This fixes a couple of minor aggravating factors that I ran across while
trying to do some changes in selftests/vm. These are simple things, but
like most things with GNU Make, it's rarely obvious what's wrong until
you understand *the entire Makefile and all of its includes*.
So while there is, of course, joy in learning those details, I thought I'd
fix these little things, so as to allow others to skip out on the Joy if
they so choose. :)
First of all, if you have an item (let's choose userfaultfd for an
example) that fails to build, you might do this:
$ make -j32
# ...you observe a failed item in the threaded output
# OK, let's get a closer look
$ make
# ...but now the build quietly "succeeds".
That's what Patch 0001 fixes.
Second, if you instead attempt this approach for your closer look (a casual
mistake, as it's not supported):
$ make userfaultfd
# ...userfaultfd fails to link, due to incomplete LDLIBS
That's what Patch 0002 fixes.
