This has broken glibc building for the `riscv64-linux-gnu' target:
iovsprintf.c: In function '__vsprintf_internal':
iovsprintf.c:34:1: error: definition in block 5 follows the use

Please submit a full bug report, with preprocessed source (by using
-freport-bug).
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.
Use just `riscv64-linux-gnu -O2' on the attached preprocessed source to
reproduce. This builds just fine up to e14afbe2d1c6^ and then breaks with
the message quoted.
Shall I investigate it further or will you be able to figure it out with
the information supplied what's wrong?
