Yes, but it seems that --coverage is passed to the command line to link
applications with CFLAGS:
[EMAIL PROTECTED]:~/src/libidn/src master$ rm idn
[EMAIL PROTECTED]:~/src/libidn/src master$ make CFLAGS="-g --coverage"
make all-am
make[1]: Entering directory `/home/jas/src/libidn/src'
/bin/bash ../libtool --tag=CC --mode=link gcc -std=gnu99 -Wall -Werror -g
--coverage -o idn idn.o idn_cmd.o ../lib/libidn.la ../gl/libgnu.la
libtool: link: gcc -std=gnu99 -Wall -Werror -g --coverage -o .libs/idn idn.o
idn_cmd.o ../lib/.libs/libidn.so ../gl/.libs/libgnu.a
make[1]: Leaving directory `/home/jas/src/libidn/src'

At least the rules in maint.mk seems to work for me in several projects.
All of them uses libtool though.
