主题: patch: fix wrong sysroot path when given rsdk toolchain

The attachment is a patch that fixes a Realtek toolchain that has a sysroot path of ‘mips-linux-uclibc’, this causes the buildroot recognizes the sysroot as ‘mips-linux-uc’ by the sed operation, and then the external toolchain setup is failed. Adding a ‘/’ in the sed re expression avoids the wrong substitution, other toolchains like linaro arm toolchain are tested ok to ensure no side effect is induced, please help review and apply this patch, thanks.
