| 4 | Subject: [PATCH] configure: Fix compoiler detection logic for |
| 5 | cross-compilation |
| 6 | |
| 7 | We can not run binaries during cross compile, so poke at compiler to |
| 8 | figure out if it is clang or gcc, for OE we do not have other compilers |
| 9 | in opensource world if there are we can extend this logic |
| 10 | |
| 11 | Upstream-Status: Inappropriate [OE-Specific] |
