[Bug 1714514] Re: math.c broken on i386, when compiling with -O2 -C

[Dimitri John Ledkov]

frama-c package, compiles jemalloc with '-C' in CPPFLAGS and thus ftbfs.
Will try to fix frama-c to not use '-C' when compiling jemalloc sub-component.
'-C' is not default CPPFLAG for jemalloc.

Bug description:
  # cat <<EOF >math.c
  #include <math.h>
  int main() {return 0;}
  EOF

  # gcc -O2 -C math.c

  expected, no output, exit code 0, like on amd64.

  Actual is exit code 1 with output:
