openblas internally sets -O2, after the flags being passed by Buildroot (e.g. -Os). Patch openblas to let the Buildroot-specified flag survive. Signed-off-by: Thomas De Schampheleire <thomas.de_schampheleire@nokia.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

Subject: [PATCH] Makefile.system: don't specify optimization level
|
|
[buildroot-specific]
|
|
|
|
Buildroot will pass an optimization level, but it is ignored because the
|
|
openblas makefiles _append_ to the flags passed on the command-line.
|
|
|
|
The CFLAGS/FFLAGS would e.g. contain '-Os -O2' in which -O2 survives.
|
|
|
|
Remove the optimization level specified in openblas itself.
