ImportError: /home/riastradh/pkgsrc/current/pkg/lib/python3.11/site-packages/numpy/linalg/_umath_linalg.so: Undefined PLT symbol "log1pl" (symnum = 20)

>How-To-Repeat:
build devel/py-boost and wonder why it fails to build boost numpy libs
>Fix:
Maybe move the kludgey log1pl wrapper from mem_overlap.c to npy_math.c?

 Module Name:	pkgsrc
 Committed By:	riastradh
 Date:		Wed May 13 02:10:58 UTC 2026

 Modified Files:
 	pkgsrc/math/py-numpy: Makefile distinfo
 Added Files:
 	pkgsrc/math/py-numpy/patches:
 	    patch-numpy___core_src_npymath_npy__math.c
 Removed Files:

 	    patch-numpy___core_src_common_mem__overlap.c

 Log Message:
 math/py-numpy: Tweak workaround for missing log2l/log1pl/expm1l.

 1. Put it in npy_math.c as needed by _umath_linalg.so.

 2. Limit it to NetBSD<10, since NetBSD>=10 has at least stubs (just
    like this workaround implements, in terms of double functions) if
    not proper long double implementations (NetBSD>=11).

 Fixes:

 >>> import numpy
 ...
 ImportError: /home/riastradh/pkgsrc/current/pkg/lib/python3.11/site-packages/numpy/linalg/_umath_linalg.so: Undefined PLT symbol "log1pl" (symnum = 20)
