ros-noetic-rospack 编译报错，需要添加-fPIC

通过yay -S ros-noetic-rospack 执行安装，以下为部份编译log

 -> error making: ros-noetic-rospack

在 /etc/makepkg.conf 中修改,加入-fPIC flag：

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fno-plt -fexceptions \
        -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security \
        -fstack-clash-protection -fcf-protection"
CXXFLAGS="-fPIC $CFLAGS -Wp,-D_GLIBCXX_ASSERTIONS"

之后使用以下命令编译

yay --makepkgconf /etc/makepkg.conf -S ros-noetic-rospack

但是报错信息相同，似乎是没有生效。
kernel信息：

 5.16.11-arch1-1

它可能自己在构建脚本里覆盖了这个设置？
