R is built daily on Fedora 21 Linux which uses glibc 2.20 and has been 
for at least a decade with that and earlier versions of glibc.  No 
problems with installing using glibc have been reported in all that time 
(and many dialects of Linux have been used successfully).

You look in config.log for the details we cannot even guess at.
