Thank you. And we now go a step further:

```
ifeq ($(ENABLE_LTO),TRUE)
ifeq ($(COM_IS_CLANG),TRUE)
gb_LTOFLAGS := -flto=thin

Yes, this is somehow misleading. It seems that COM_IS_CLANG is set nervertheless. Should be fixed, but since all archs in Debian *do* have clang and that one is used this wasn't yet an issue.

And I disbale CLANG in d/rule:

```
# generally use clang
USE_CLANG=n
# allow clang for skia?
ALLOW_CLANG=n

CLANG_VERSION=default

```

Which is in effect since the error message clearly says g++.

not using clang is the exception from the rule.


You can set ENABLE_LTO=n to get it built without LTO, though.


Ok, my fix is very buggly:

```
ifeq "$(ENABLE_MERGELIBS)" "y"
# vimer: fix
 ENABLE_LTO=n
else
 ENABLE_LTO=n
endif
```

Well enough. Because `ENABLE_LTO` will affect LTO only in here. it would
be better to disable LTO depend on ARCH.

Luckily, We got the *bridge* part:
