We have an existing patch to configure.in that chains the test to find
fltk (supposedly because a symbol of fltk got renamed sometime in the
past). By doing so, this chaining breaks the build when configure later
checks for the alsa libraries.
This is because chaining calls to AC_CHECK_LIBS() one in the other would
be expanded in such a way that internal functions, like ac_fn_c_try_link,
would get defined after being called, which results in configure failures
(see new bundled patch).
So, we change configure to use AC_SEARCH_LIBS() instead, which allows us
to memorise the result of each test, and we only fail when both tests
failed.
We can now drop the ac_cv overrides we had.
Incidentally, this also fixes detection of newer alsa-libs, where
atopology functions were offloaded to their own separate library:

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
