ed2b922537 make_single_applets: fix ": $((fail++))" expansion error 
$((fail++)) is not a required expression in POSIX, and in "dash" it
could produce an error like this:

    ./make_single_applets.sh: 61: arithmetic expression: expecting primary: "fail++"

Replace this with something portable: fail=$((fail+1)) would work.

e9a25ac924 Makefile: include per-arch Makefile before Makefile.flags 
Makefile.flags contains:

ARCH_FPIC ?= -fpic
ARCH_FPIE ?= -fpie

However, arch/$(ARCH)/Makefile gets included *after* Makefile.flags,
and therefore doesn't get the chance to provide its own value.

Fix this by including arch/$(ARCH)/Makefile *before* Makefile.flags.
