0002-Add-configure-time-check-for-lanl.patch (taken from mosquitto
PR #3358) probes for -lanl with a $(shell ...) that pipes a small C
program into $(CC):
NEED_LIBANL := $(shell printf '#include <stdlib.h>\n#include <netdb.h>\n...
The test program contains literal '#' characters. GNU make strips
comments before expanding functions, and only since 4.3 does it keep
'#' inside a function call argument intact. With older make the line
is truncated at the first '#', so the shell call never sees its
closing parenthesis:
config.mk:322: *** unterminated call to function 'shell': missing ')'. Stop.
That is why the package builds fine locally (make 4.3+) but fails on
the build server, which ships an older GNU make.
Switch to the variant that was actually merged upstream (commit
dfde35a, "Add compile time checks for whether -lanl is required").
It links an empty main() against -lanl instead of compiling a program
that calls getaddrinfo_a(), so the test source needs no #include and
contains no '#' at all, which works on every make version.

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 https://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 OFTC IRC.
