Fabrice Fontaine 1d3d2d2741 package/bird: fix build with autoconf >= 2.70 ... Fix the following build failure raised since bump of autoconf to version 2.71 in commit ecd54b65c1: checking for glob.h... no configure: error: glob.h not found. 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' This is the same problem that we tried to fix in 03c148c8de by adding AUTORECONF = YES. The analysis made back then is probably not entirely correct - the issue only seems to occur with GCC8, not with any earlier or later version, which hints at a compiler bug. Since the error involves some LTO-generated functions, the trigger is probably the -flto=4. Whatever the exact issue is, it is avoided if we make sure that our CFLAGS replace the default ones instead of being added to them. Currently, they are added because the configure script doesn't properly detect that CFLAGS was set. Add a patch (sent upstream months ago, but it didn't appear in the release that has been done since then) that makes sure CFLAGS is properly detected.
