Subject: python3: add patch to fix --includes / --ldflags output of python3-config
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fbb8cbfdf4ef0be10d2e9b8e51cde98d2909a120;p=buildroot.git

python3: add patch to fix --includes / --ldflags output of python3-config

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.
