For what it's worth, the problem seems to depend on the combination of
-DNO_NOTRETURN=1 and -fprofile-use.  So I can trigger the same breakage
with this:
---
#define NO_NORETURN 1
#include "git-compat-util.h"

int main() {}
---
gcc -I. -c -fprofile-use=/tmp foo.c -o foo.o

Do we still need NO_NORETURN?  Git seems to build without it under GCC
4.6.3 (Ubuntu's version).
