尝试构建基于LoongArch64架构Linux系统桌面办公软件libreoffice

1 设置环境变量
```shexport LDFLAGS="-Wl,-rpath-link=${SYSDIR}/sysroot/usr/lib64"export PKG_CONFIG_SYSROOT_DIR=${SYSDIR}/sysrootexport PKG_CONFIG_PATH="${SYSDIR}/sysroot/usr/lib64/pkgconfig:${SYSDIR}/sysroot/usr/share/pkgconfig"export COMMON_CONFIG="--prefix=/usr --sysconfdir=/etc --localstatedir=/var --libdir=/usr/lib64 \                      --build=${CROSS_HOST} --host=${CROSS_TARGET}"export JOBS="-j8"```

2 LibreOffice
获取软件代码。
```shgit clone https://git.libreoffice.org/core --depth 1pushd coregit submodule initgit submodule update --depth 1popdmv core libreoffice-7.5-gittar -czf ${DOWNLOADDIR}/libreoffice-7.5-git.tar.gz libreoffice-7.5-git```
编译和安装。
```tar xvf ${DOWNLOADDIR}/libreoffice-7.5-git.tar.gz -C ${BUILDDIR}pushd ${BUILDDIR}/libreoffice-7.5-git
