%description
This package extracts glibc, glibc-common, glibc-devel and glibc-headers binary
RPM payload archives into the private gcc-toolset-7 sysroot layout used on openEuler 24.03.
It is intended to provide the libc runtime, crt objects, linker scripts and
headers needed by the devtoolset-7 GCC build flow.
