[Buildroot] cyrus-imapd in buildroot: imtest does not cross-compile correctly

[Luca Ceresoli <luca@lucaceresoli.net>]

Hi,

trying to cross-compile cyrus-imapd 2.4.9 in buildroot, with most options
disabled to keep things simple, I got this:

   [...]
   ### Making install in /home/murray/devel/buildroot/output/build/cyrus-imapd-2.4.9/imtest
   make[2]: Entering directory `/home/murray/devel/buildroot/output/build/cyrus-imapd-2.4.9/imtest'
   /usr/bin/install -c -s -m 755 imtest /home/murray/devel/buildroot/output/target/usr/bin
   strip: Unable to recognise the format of the input file `/home/murray/devel/buildroot/output/target/usr/bin/imtest'
   /usr/bin/install: strip process terminated abnormally
   make[2]: *** [install] Error 1
   make[2]: Leaving directory `/home/murray/devel/buildroot/output/build/cyrus-imapd-2.4.9/imtest'
   [...]

Clearly, the host install (/usr/bin/install) is being used and it is normal that
it fails in stripping cross-compiled files.
What I don't know is how to tell ./configure that it should not instruct install
to strip files, i.e. not pass the -s option.

After a very brief research, I cowardly opted for patching cyrus-imapd to
completely disable imtest compilation, as I don't need it.

Any idea on how to really fix this issue, instead of just disabling imtest?
And how about adding a --disable-imtest option?

Attached are the build log and my awful patch.

Luca
