[Buildroot] how to change compiler flags for a specific package

[Sven Neumann]

Hi,

I have a question about buildroot. I need to compile a specific package
with different compiler flags than the default. By default -Os is used
in my buildroot setup, but as this triggers a compiler bug when
compiling flac, I would like to change this to -O2 for the flac package
(which uses Makefile.autotools.in). What is the best way to do that?

For what arch, and what goes wrong exactly?

You can probably put your alternative CFLAGS in FLAC_MAKE_ENV or
FLAC_MAKE_OPT to get the package to use it.

I'll try that. Thanks.
