There is no /Developer on 10.9/Xcode 6.2. Any clang there is not part of
Apple's default build tools setup. Apple's clang lives in
/usr/bin/clang, which is a stub for
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang.

Fink on purpose is designed to ignore as much as it can of a user's
local setup, especially things like PATH and other ENVVARS. However, it
can't deal with actual changes to the filesystem.
What is the output of (this is a one line command):
ls -l
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
/usr/bin/clang
and
/usr/bin/clang --version

The `ls -l` command shows "clang" in neither of the two paths.
I have now idea where the version of clang in /Developer/usr/bin came
from (I can't imagine other than from Apple). Nevertheless, when I copy
it to /usr/local/bin, where fink presumably can find it, I still get the
"C compiler cannot create executables" error.
I've used fink for years, and never had this problem. The only
connection I can think of is that I probably upgraded to Xcode 6.2 since
I had prexiously done a "fink update-all". (Apple says Xcode 6.4 is not
compatible with OS 10.9.5. That is, 6.2 is the most up-to-date version
for my OS.)
I am to infer from yor comments that clang is not a part of the Xcode
package?

No, it?s part of Xcode and has been the compiler that we?ve used since 10.7.
On 10.7 and 10.8 (I believe) /Developer/usr/bin was a thing, so maybe that?s a
holdover from a prior OS. If you checked in the config.log you might see a
different error than before from using an outdated clang.
It sounds like maybe your Xcode command-line tools need reinstallation. See if
?sudo xcode-select --install? works, and if not, you?ll need to download them
again from developer.apple.com

Any kludging is on Apple?s part. You probably need to create a /usr/bin/ld
symlink.
That being said, my Xcode + Xcode Tools installs have always set things up
appropriately in /usr/bin, and that has been the case for most people.
A reason we don?t put /Applications/Xcode.app/?/bin into the PATH is that we
don?t actually require Xcode.app to be installed.
Oh, and /usr/bin/ld shows up here as being installed by the system, at least as
a stub:
Fionna:~ hansen$ which ld
/usr/bin/ld
Fionna:~ hansen$ pkgutil --file-info /usr/bin/ld
volume: /
path: /usr/bin/ld
pkgid: com.apple.pkg.Essentials

Is /usr/bin/ld completely absent for you?
