ext-toolchains: take into account other Glibc dynamic loader variants

External toolchains using Glibc have different names for the dynamic
loader. Some of them name it ld-linux.so.*, while some others (such as
the PowerPC and MIPS CodeSourcery toolchains) name it simply ld.so.*.

Therefore, we fix the glibc detection code to handle this case.
