it does in glibc-2.15 and earlier:
$ readelf -sW /lib64/libc.so.6
   110: 00000000000e9310    91 FUNC    GLOBAL DEFAULT   11 _mcount@@GLIBC_2.2.5
  1960: 00000000000e9310    91 FUNC    WEAK   DEFAULT   11 mcount@@GLIBC_2.2.5

which means  __mcount_internal@GLIBC_PRIVATE makes no sense because nothing
external to glibc is referring to it

whether a random glibc git version exported it doesn't matter as we only care
about compatibility with releases
