Fix Linux build error with musl libc

Commit bf5953c549a6d279977df69ffe89b2ba51460eaf caused a build failure
on non-glibc Linux build environments.  Change the conditionalization
so that __GLIBC_PREREQ will only be used if it is defined.

[ghudson@mit.edu: simplified conditionals; rewrote commit message]
