[Qemu-devel] [PULL 28/38] configure: handle clang -nopie argument warning |
Date: |

gcc 4.9.2 treats -nopie as an error:
cc: error: unrecognized command line option ‘-nopie’
clang 3.5.0 treats -nopie as a warning:
clang: warning: argument unused during compilation: '-nopie'
The causes ./configure to fail with clang:
ERROR: configure test passed without -Werror but failed with -Werror.
Make the -nopie test use -Werror so that compile_prog works for both gcc
and clang.
