Problem found.
In the *) part of the target case which I used as base for *-ecos*) did not 
set SECTION_FLAGS/SECTION_LDFLAGS. So they were empty. When I added them 
the first time I just did it in the multilib definition file(t-ppcgas). 
That explains why it was set for all but the default.

However I am still not able to get --gc-sections to do as it should. When I 
split up the functexcept.cc file it works fine. Then I only get 
__throw_bad_alloc. I have checked that the library actually has one section 
pr. function and that is true. So I wonder what other possible errors could 
I have made.
I am using target.ld file that is provided by ecos. It seems pretty 
straight forward. A few KEEP() but that is for the exception vectors and 
dor the ctors/dtors.
Any ideas ?
