[New-bugs-announce] [issue22907] Misc/python-config.sh.in: ensure sed invocations only match beginning of strings

[Peter Korsgaard]

New submission from Peter Korsgaard:

The build/real prefix handling using sed breaks if build != real and the
standard include / lib directories are used ($prefix/include and $prefix/lib).

E.G.

prefix_build="/usr", libdir="$prefix/lib", includedir="$prefix/include".

If this gets installed with make DESTDIR="/foo" install, then we end up with prefix_real = prefix = "/foo/usr" as expected, but
includedir="/foo/foo/usr/include" and libdir="/foo/foo/usr/lib" because of the double sed invocation (prefix is already expanded).  Work around it by ensuring we only match the beginning of the string.
