For certain architectures we need to mangle the opts to get working binaries.
|
||
|
|
This is for example the case on mips, where we need -mnoabi-calls if we
|
||
|
|
do not want get segfaults ... Alternatively instead of injecting the generic
|
||
|
|
-Os battery of options we could define fine-grained injections in our build
|
||
|
|
system but I find working with up-stream people and those defaults might be
|
||
|
|
the better choice.
