in reality I was fooled by the stub,
the stripped version is ~ 1M insted of 5M

$ du -sb inst/usr/bin/gprof.exe
1146387 inst/usr/bin/gprof.exe

there is a trace of previous setting before "all" in the cygport

# 
--enable-targets=i686-efi-pe,x86_64-efi-pe,ia64-efi-elf,x86_64-pc-cygwin,i686-pc-cygwin
