[Buildroot] [PATCH 1/1] package/bird: needs autoreconf

[Fabrice Fontaine]

For an unknown reason, autoreconf is needed since bump to version 2.0.8
in commit f5906644b45269b1a5fe109cb64fad837e4fbff2 to avoid the
following build failure:

checking for glob.h... no
configure: error: glob.h not found.

This build failure is raised because -g0 and -g are both passed to gcc:

configure:5207: checking for glob.h
configure:5230: /data/buildroot-autobuilder/instance-0/output-1/host/bin/mips64el-linux-gcc -o conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Os -g0  -pthread -fno-strict-aliasing -fno-strict-overflow -flto -Wall -Wextra -Wstrict-prototypes -Wno-parentheses -Wno-pointer-sign -Wno-missing-field-initializers -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -pthread -flto=4 -g conftest.c  >&5
/data/buildroot-autobuilder/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips64el-buildroot-linux-uclibc/8.4.0/../../../../mips64el-buildroot-linux-uclibc/bin/ld: /tmp/ccDboxph.ltrans0.ltrans.o:(.debug_info+0x2a): undefined reference to `conftest.c.0943dc99'
/data/buildroot-autobuilder/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips64el-buildroot-linux-uclibc/8.4.0/../../../../mips64el-buildroot-linux-uclibc/bin/ld: /tmp/ccDboxph.ltrans0.ltrans.o:(.debug_info+0x2f): undefined reference to `conftest.c.0943dc99'

-g0 is passed by buildroot and -g is passed by bird if
$ac_test_CFLAGS" != set (since version 2.0.7 and
https://gitlab.nic.cz/labs/bird/-/commit/cc95b4594ac924b40325a4f1adcae5312179db40)

For an unknown reason without autoreconf, ac_test_CFLAGS doesn't seem to
be equal to "set"
