We don't want to have local changes to the files from tzcode. Presumably
this is from the -std=gnu11, which sets __STDC_VERSION__ but was
incomplete in GCC 4.8. I think requiring GCC >= 4.9 and binutils >= 2.25
(the latter given internal linker errors on x86 with 2.24) is reasonable
for building glibc.
