Fabrice Fontaine be5e0230c6 package/boinc: fix build with autoconf >= 2.70
Fix the following build failure raised since bump of autoconf to version
2.71 in commit ecd54b65c1 and
http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=commit;h=ec90049dfcf4538750e61d675d885157fa5ca7f8:

checking for /home/buildroot/autobuild/instance-0/output-1/host/bin/mips-linux-gnu-gcc options needed to detect all undeclared functions... cannot detect
configure: error: in `/home/buildroot/autobuild/instance-0/output-1/build/boinc-7.16.18':
configure: error: cannot make /home/buildroot/autobuild/instance-0/output-1/host/bin/mips-linux-gnu-gcc report undeclared builtins

This error raised because AC_CHECK_DECLS returns an error due to -mavx
flag:

mips-linux-gnu-gcc: error: unrecognized command line option '-mavx'

To fix this build failure, hard code ac_cv_c_undeclared_builtin_options
to 'none needed' as removing '-mavx' from CPPFLAGS will hinder the
detection of xgetbv, xgetbv, __xgetbv, cpuid, _cpuid and __cpuid

Fixes:

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 OFTC IRC.
