linker stripping shared libraries by default

[Guennadi Liakhovetski]

Hi all

Using "Sourcery G++ Lite 4.4-200" and trying to build executables and 
libraries with debugging information in them for profiling, I notice, that 
my object files are built unstripped, but the final ld call to link a 
library produces a stripped shared library. Here's an excerpt:

sh-linux-gnu-gcc -I. -I"/some-path/ffmpeg-shared" -D_ISOC99_SOURCE \
-D_POSIX_C_SOURCE=200112 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE \

Any pointers?
