Dongsu Park dd15b2ee4d eclass: remove also other optimization flags with -Wl,-O* ... We need to filter not only `-Wl,-O1`, but also other flags like `-Wl,-O2`, `-Wl,-Og`, `-Wl,-Os`, etc. Otherwise, SDK build would fail, for example, as its default `$LDFLAGS` includes `-Wl,-O2`. We need to manually strip only the optimization element of comma-separated flags, e.g. from `-Wl,-O1,-s` to `-Wl,-s`. To support multiple characters that can follow `-O`, e.g. `-Ofast`, we should use regexp like `[[:alnum:]]*`.		2020-11-16 13:07:04 +01:00
