misbuilds when /bin/sh -> bash
Binary package hint: libtool
When /bin/sh is a symlink to bash, libtool finds that /bin/sh supports the features it needs and hence hardcodes it as the #! line of /usr/bin/libtool. If /bin/sh is later changed to be a symlink to dash, this breaks because dash does not support "var+=value" syntax. This broke dictd during the Ubuntu armel bootstrap:
libtool --tag=CC --mode=link gcc -o dict -static \
dict.o net.o clientscan.o clientparse.o md5.o wcrtomb.o wctomb.o mbrlen.o mbrtowc.o mbstowcs.o mbtowc.o iswspace.o iswalnum.o towlower.o strlcpy.o strlcat.o parse.o \
-Wl,-z,defs -Wl,--as-needed -Llibmaa -lmaa -ldl -lz
eval: 1: libtool_args+=: not found
I worked around this as follows:
libtool (2.2.4-0ubuntu5) jaunty; urgency=low
* Force /bin/bash as the shell for the generated libtool script, even if
/bin/sh happens to be bash on the build system.

... but it perhaps needs a proper fix in libtool to detect this at run-time.
This sort of reminds me of http://
