Use flags suitable for armhf port when TARGET=ARMV6

Forwarded: not-needed
Last-Update: 2015-04-29

See debian/rules for an explanation of why we can't use TARGET=ARMV7 on armhf.
Also, if we don't explicitly set the -march and -mfpu flags, the resulting
static libraries crash with SIGILL (reason not yet elucidated).
