我已经使用crosstool-NG 1.24.0构建了sdk
target:
Architecture- i686 (32 bit amd)
Binutils:2.32
kernel: 4.9.156
Glibc: 2.19
Gcc: 7.4.0
SDK构建成功。现在我正在尝试交叉编译python-3.6.9

首先，这是什么意思
/usr/include/i386-linux-gnu/sys/cdefs.h:467:49: error: missing binary operator before token "("
#if __GNUC_PREREQ (4,8) || __glibc_clang_prereq (3,5)
相关问题here，但不幸的是没有答案...
第二个为什么它引用以下路径，尽管我将CPPFLAGS设置为sysroot / include
/usr/include/i386-linux-gnu/sys/cdefs.h

我在

我的SDK位于

如何解决此参考问题？
谢谢
