            Bug ID: 30196

elfutils-0.189-fix-configure-bashisms.patch

Autoconf scripts are supposed to be written in POSIX-compatible shell langu=
age.
elfutils commits 0ffe2874e75d48cb88936e119e5284ff2bf664d9 and
3fa98a6f29b0f370e32549ead7eb897c839af980 introduced Bashisms to configure.ac
that cause errors when /bin/sh is not Bash.

Example error when /bin/sh is Dash:

./configure: 8748: test: xyes: unexpected operator


The cause of the error is the use of a non-existent =3D=3D operator in expr=
essions
passed to the 'test' built-in command. POSIX shell specifies only an =3D op=
erator
for testing string equality.

Please make the corrections indicated in the attached patch.
