A small correction: -shared overrides any profiling option at the linking
stage.  The cc1 option -p is added for all of -p/-pg/-profile (for the first
two automatically, for the third there is a rule in the specs file).

I verified equivalent behaviour on Linux and the Hurd for the following:

gcc -v -o main main.c $(OPTIONS)

Where $(OPTIONS) is:
(any combination of the above)
-shared -p/-pg/-profile/combinations
-static -p/-pg/-profile/combinations

At least I believe so.  I will double check tomorrow.
