在 armbian 下交叉编译 QT 时出现 lib-names-soft.h 问题

QT5.12.3我为设备编译armbian。对于配置 ( ./configure)，我使用以下选项：

./configure -prefix /home/asianirish/Install/qt5/qtbase -opensource -confirm-license \
    -debug \
    -prefix /home/asianirish/Qt-custom/qt-embedded-5.12.3 \
    -sysroot /home/asianirish/img/armbian \
    -c++std c++11 \
    -device linux-arm-generic-g++ \
    -device-option CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- \
    -openssl \
    -no-widgets \
    -no-gif -qt-libpng -qt-libjpeg \
    -no-opengl \
    -skip qtwebengine \
    -nomake examples \
    -v

配置以成功结束：

/*
Note: Also available for Linux: linux-clang linux-icc

Note: No wayland-egl support detected. Cross-toolkit compatibility disabled.

WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.

Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/home/asianirish/img/armbian/home/asianirish/Qt-custom/qt-embedded-5.12.3'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

但是执行后make会报错：

...

我进去了/usr/arm-linux-gnueabihf/include/gnu/，可以肯定的是，只有谎言lib-names-hard.h，lib-names-soft.h那里没有！

>pwd
/usr/arm-linux-gnueabihf/include/gnu
>ls
libc-version.h  lib-names-hard.h  stubs-hard.h
lib-names.h     stubs.h           stubs-soft.h

这是什么lib-names-soft.h？我爬进去lib-names.h看看：

#if !defined __ARM_PCS_VFP
# include <gnu/lib-names-soft.h>
#endif
#if defined __ARM_PCS_VFP
# include <gnu/lib-names-hard.h>
#endif

我用谷歌搜索__ARM_PCS_VFP，发现这是一种使用浮点数的方法——硬件或软件。好吧，好吧，我决定做一个肮脏的 hack - 我linux_device_post.conf在文件中添加一行（来自开源 QT 包）：

#Внимание, грязный хак, не повторяйте!
QMAKE_CFLAGS        += -mfloat-abi=hard

但是，正如预期的那样 - 失败：

/*

make[3]: *** [../../lib/libQt5Core.so.5.12.3] Error 1

有没有人遇到过这样的问题？哪里可以买到这个 lib-names-soft.h？我认为滑倒它会是一个更肮脏的黑客，所以我什至不会尝试。也许在配置中更改它-device-option？或者-device？为了什么？在哪里挖？
