# Modify curl-config to make it architecture-independent:
# 1. In --static-libs output, replace the output of krb5-config (which
#    currently includes architecture-specific paths) with a call at
#    runtime to krb5-config.  Of course, this will only work correctly
#    if the installed libkrb5-dev matches the architecture of the
#    program you're linking, or if libkrb5-dev is made
#    multiarch-compatible at some point in the future.  For dynamic
#    linking this has no impact.
# 2. In --configure output, replace the architecture-specific paths
#    used for --libdir and --libexecdir with a literal backquoted call
#    to dpkg-architecture.  This is functionally equivalent to the way
#    debhelper actually invokes configure, and indicates to the user
#    (who runs curl-config --configure in order to learn about how the
#    library was compiled) that they are in fact using a multi-arch
#    package.
# 3. Likewise, replace the architecture name used for --build (and
#    build_alias) with a literal backquoted call to dpkg-architecture.
# 4. In --configure output, remove
#    -fdebug-prefix-map=/buildd/specific/random/path=.
