Subject: tests: drop `BUNDLE_SRC` variable
X-Git-Tag: rc-8_15_0-1~4
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=7d8fa8276d4df7a89056ef4bfd1fee47efd56aa6;p=thirdparty%2Fcurl.git

tests: drop `BUNDLE_SRC` variable

Derive it from `$BUNDLE` instead. autotools seems to be already relying
on `$BUNDLE_SRC` being equal to `$BUNDLE.c`. (I haven't realized this
before aaebb45f58b3f62876a68c17c71ac37d98f1b3bb.)

Also drop redundant `nodist_<target>_SOURCE` lines in tunits and units.

Follow-up to aaebb45f58b3f62876a68c17c71ac37d98f1b3bb #17688
Follow-up to 2c27a67daa1b76859c18d63e4e1f528db05b5e13 #17590

Closes #17692
