$(objpfx) directories, and get rid of vpath directives. The previous arrangement resulted in files being written to the source directories when run in a clean build. Find all .abilist files in $(..)abilist/. (update-abi-%): Likewise. (generated): Don't add .symlist files, they'll be intermediates. * sysdeps/generic/init-first.c: Add a comment. * elf/Makefile ($(objpfx)ld.so): Pass -z defs in link. * scripts/gen-as-const.awk: Grok lone "--" as a separator between #includes and expressions. * scripts/merge-abilist.awk: Omit cpu-.*-os.*/modifier from merged config list when it already contains cpu-.*-os.* without / part. * Makerules (sed-remove-dotdot): New variable. ($(common-objpfx)%.make): Use it. Depend on $(before-compile). ($(common-objpfx)%.h $(common-objpfx)%.h.d): Likewise. (check-abi-config): New variable, append /tls or /notls to the tuple. (check-abi-%): Use that for -v config value. Find .abilist files in abilist/libfoo.abilist, not in subdir. * Rules: Move bits/stdio_lim.h generation rules to Makerules.
