lttng-ust: [PATCH] Fails to build while relinking, needs `PKG_FIXUP:=autoreconf`, in 22.03

Maintainer:

No maintainer specified in package/feeds/packages/lttng-ust/Makefile, see issue #18940.

Environment:

• Building for Xunlog OrangePi Plus (sun8i):
  grep ^CONFIG_TARGET .config:

  CONFIG_TARGET_sunxi=y
  CONFIG_TARGET_sunxi_cortexa7=y
  CONFIG_TARGET_sunxi_cortexa7_DEVICE_xunlong_orangepi-plus=y
  CONFIG_TARGET_BOARD="sunxi"
  CONFIG_TARGET_SUBTARGET="cortexa7"
  CONFIG_TARGET_PROFILE="DEVICE_xunlong_orangepi-plus"
  CONFIG_TARGET_ARCH_PACKAGES="arm_cortex-a7_neon-vfpv4"
  [...]
  

• OpenWrt version:
  • Git branch openwrt-22.03 from git://git.openwrt.org/openwrt/openwrt.git,
  • initially checked out on 2022-07-05,
  • latest git pull and ./scripts/feeds update -a && ./scripts/feeds update -a on 2022-07-14, ca. 12:00 UTC
    (I give up on posting latest commit date and hash, since git log gives me some old dates, and I don't know how I can make git log printing out the last operation. I don't know much about git.)
• Building on GNU/Linux on x86_64-architecture (Distribution: Artix Linux).
• OpenWrt configuration: → config.txt.
• grep -i lttng .config:

  CONFIG_PACKAGE_lttng-tools=m
  CONFIG_PACKAGE_lttng-ust=m
  

Description:

After a make dirclean, a subsequent make -j6 fails in above configuration on package/feeds/packages/lttng-ust. After a make package/feeds/packages/lttng-ust/clean, an explicit run of
make -j1 V=sc package/feeds/packages/lttng-ust/compile
fails with

libtool:   error: error: relink 'liblttng-ust.la' with the above command before installing it
make[5]: *** [Makefile:570: install-libLTLIBRARIES] Error 1

Full output of above make command is too long to be pasted here, so it is attached: → lttng-ust.compile.log.

Start with package/feeds/packages/lttng-ust/Makefile and review the attached lttng-ust.compile.log alongside the failing package/feeds/packages/lttng-ust/compile command. Reproduce the relinking failure with make -j1 V=sc, then verify that the package builds successfully after the build-system adjustment.
