[gccsdk] !SharedLibs ReadMe and soname

[Ron]

The !SharedLibs ReadMe is very helpful for a newcomer to understand
it's purpose.
However I found the paragraph explaining how to use the -soname=
option completely wrong.
If "/" is used, the lib will not load for either use by gcc at
linking, or for the executable that is linked to it.
You must use,  -soname=libefg.so [.so.1.2] syntax. 

For linking you can just use -lefg, and avoid the need to
get around gcc treating libefg/so as a directory.
Actually simply renaming to libefg for -I would work, but it is
simpler to just use SharedLib: and avoid the translations
altogether.
The next step will be to write the shared object (libefg/so)
and any links directly to SharedLib:lib/ instead of producing
it in the CSD. (untried) 

>From the point of view of GCC, everything is in . files.
with no deviation. "/" is a directory

I haven't found the reason, wether unixlib or GCC, but when
there is a gcc command error, it reports back with "/"
instead of "." in the supposed file causing the error.

It's not a show stopper, but it would be better if it kept
to the same theme, I think.
