[PATCH] selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)

[Ilya Leoshkevich]

The current logic prepends $(OUTPUT) only to the first member of
$(TEST_PROGS). Use $(foreach) loop to prepend it to each member.

Fixes: 1a940687e424 ("selftests: lib.mk: copy test scripts and test files for make O=dir run")

Hmm. with this patch there is a regression:

make kselftest O=/tmp/kselftest TARGETS=splice

fails for me with


TAP version 13
1..1
# selftests: splice: splicedefault_file_splice_read.sh
# Warning: file /tmp/kselftest/splicedefault_file_splice_read.sh is missing!
not ok 1 selftests: splice: splicedefault_file_splice_read.sh
make[1]: Leaving directory '/tmp/kselftest'

Without your patch works just fine:

make kselftest O=/tmp/kselftest TARGETS=splice
make[1]: Entering directory '/tmp/kselftest'
make --no-builtin-rules INSTALL_HDR_PATH=$BUILD/usr \
	ARCH=x86 -C ../../.. headers_install
   INSTALL /tmp/kselftest/usr/include
gcc     default_file_splice_read.c  -o 
/tmp/kselftest/splice/default_file_splice_read
TAP version 13
1..1
# selftests: splice: default_file_splice_read.sh
ok 1 selftests: splice: default_file_splice_read.sh
make[1]: Leaving directory '/tmp/kselftest'
