The host-autoconf-archive package was added to provide the necessary
autoconf macros for the libsigrok package, and later also used for the
thrift package.
However, it installs its autoconf macro in
$(HOST_DIR)/usr/share/aclocal, which is part of the include directory
of autoconf macros used for all autoreconf invocations. Unfortunately,
using those macros for all packages is causing a number of
regressions: one on host-ola fixed in commit
884af65fd5, and one in snmpp. Those
packages are autoreconf'ed, but if they are autoreconf'ed with the
autoconf-archive macros installed, they no longer work.
To solve this problem, this commit implements a simple solution that
makes using host-autoconf-archive macros an opt-in mechanism. To
achieve this, the autoconf-archive package is modified to install its
macros in a special directory, and only the packages that really want
to use those macros will have to pass a -I flag pointing to this
directory in their <pkg>_AUTORECONF_OPTS variable.

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.
