Yann E. MORIN says:

    "Although eglibc can be configured to include/exclude parts of the
    features, it seems to not be in wide use, if at all."

v4: now actually commit the rephrased text.

v3: rephrase the help text to make it clear that the eglibc build is given,
    address the comment of Thomas Petazzoni.

v2: mention in the help text that eglibc may lack some features as suggested
    by Yann E. MORIN.
