Use __GLIBC_PREREQ only when __GLIBC__ is defined
The way __GLIBC_PREREQ() is currently used means that it's evaluated
even if __GLIBC__ is not defined. But obviously, __GLIBC_PREREQ will
not exist if __GLIBC__ is not defined, causing build failures on C
libraries not defining __GLIBC__ such as the musl C library.
