下载源码包 glibc:
Contains the standard libraries that are used by nearly all programs on the system. This package includes shared versions of the standard C library and the standard math library, as well as many others.
This set of libraries is optimized for the UltraSPARC v9b ABI. It only needs to be installed on UltraSPARC machines. If you install this on a non-UltraSPARC, it won't even be used.
