Late night comment, Paolo, I think your patch is fine but it exposed an
inconsitency in using CFLAGS/BOOT_CFLAGS in libgcc.
I could work around the problem with filtering out the mdynamic-no-pic inside
the libgcc Makefile.in.:

 # Forcibly remove any profiling-related flags.  There is no point

-override CFLAGS := $(filter-out -fprofile-generate -fprofile-use,$(CFLAGS))
+override CFLAGS := $(filter-out -fprofile-generate -fprofile-use
-mdynamic-no-pic,$(CFLAGS))

 # CFLAGS first is not perfect; normally setting CFLAGS should override any
 # options in LIBGCC2_CFLAGS.  But LIBGCC2_CFLAGS may contain -g0, and CFLAGS

It's absolutely the wrong place with the wrong comment. But it's ok for a first
trial.

It smells for me to have an additional var and to pass this one correctly to
all involved consumers.

As said, late night.
