Bug#1050992: hwcap default search paths changed
Source: glibc
Version: 2.37-1
Previously defined hwcap search paths have been changed. Those
specified in `man 8 ld.so` are no longer accurate (bug #1050930).
Typical output on sid/i386:
% LD_DEBUG=libs LD_LIBRARY_PATH=. /bin/true
3611433: find library=libc.so.6 [0]; searching
3611433: search path=. (LD_LIBRARY_PATH)
3611433: trying file=./libc.so.6
3611433: search cache=/etc/ld.so.cache
3611433: trying file=/lib/i386-linux-gnu/libc.so.6

Same goes for:
[...]
% /lib/ld-linux.so.2 --help | tail
This program interpreter self-identifies as: /lib/ld-linux.so.2
Shared library search path:
(libraries located via /etc/ld.so.cache)
/lib/i386-linux-gnu (system search path)
/usr/lib/i386-linux-gnu (system search path)
/lib (system search path)
/usr/lib (system search path)
No subdirectories of glibc-hwcaps directories are searched.
[...]
If I understand correctly, this render the following .so file obsolete (unused):
% file /usr/lib/i386-linux-gnu/i686/sse2/libx264.so.164
/usr/lib/i386-linux-gnu/i686/sse2/libx264.so.164: ELF 32-bit LSB
shared object, Intel 80386, version 1 (SYSV), dynamically linked,
BuildID[sha1]=e66974d10aef77af7ed504266cde974d103484d6, stripped
Possibly other packages might be impacted.
I suspect the best upgrade path is simply to document the old hwcap
search path have been removed, and Debian package(s) should not rely
on them anymore (lintian warning?).
Comments ?
