How about removing the profile-all target and making it a build option
instead? To enable it, do the usual:

 echo PROFILE_BUILD=YesPlease >> config.mak
 echo prefix=... >> config.mak
 make
 su make install

In the Makefile, we would have

ifdef PROFILE_BUILD
 all:
	$(MAKE) CFLAGS=... -fprofile-generate ... all-one
	$(MAKE) CFLAGS=... -fprofile-use ... all-one
else
 all: all-one
endif

and each previous instance of 'all' replaced with 'all-one'.
