ldconfig: set LC_COLLATE to C [BZ #22505]
ldconfig supports `include' directives and use the glob function to process them. The glob function sort entries according to the LC_COLLATE category. When using a standard "include /etc/ld.so.conf.d/*.conf" entry in /etc/ld.so.conf, the order therefore depends on the locale used to run ldconfig. A few examples of locale specific order that might be disturbing in that context compared to the C locale: - The cs_CZ and sk_SK locales sort the digits after the letters. - The et_EE locale sorts the 'z' between 's' and 't'. This patch fixes that by setting LC_COLLATE to C in order to process files in deterministic order, independently of the locale used to launch ldconfig. NOTE: This should NOT be backported to older release branches. Changelog: [BZ #22505] * elf/ldconfig.c (main): Call setlocale to force LC_COLLATE to C.
