toolchain-external: fix broken handling of 'usr/lib/locale'
Function copy_toolchain_sysroot, which is in charge of copying the relevant bits from the external toolchain to the staging directory, performs an rsync loop of various directories and excludes the pattern 'usr/lib/locale' with the intention of skipping the directory <toolchain>/usr/lib/locale. However, while this worked in the original commit, commit 5628776c4a4d29d0715633ea463b64cc19e19c5a broke it inadvertently. The relevant part of the diff: - rsync -au --chmod=Du+w --exclude 'usr/lib/locale' \ - $${ARCH_SYSROOT_DIR}/$$i $(STAGING_DIR)/ ; \ + rsync -au --chmod=Du+w --exclude 'usr/lib/locale' \ + --exclude lib --exclude lib32 --exclude lib64 \ + $${ARCH_SYSROOT_DIR}/$$i/ $(STAGING_DIR)/$$i/ ; \ Notice how the source directory now contains a trailing slash, which impacts the way the exclude rules are interpreted. Previously, when 'i' was 'usr', the exclude of 'usr/lib/locale' would find a match. With the trailing slash, there will never be a match, unless for a directory 'usr/usr/lib/locale'. The right rule would have been '--exclude lib/locale'. However, just that fix does not solve the problem in all cases, in particular in the (common) case where ARCH_LIB_DIR is 'lib'. This is due another change in that commit, changing the iterated values of the above rsync: - for i in etc $${ARCH_LIB_DIR} sbin usr ; do \ + for i in etc $${ARCH_LIB_DIR} sbin usr usr/$${ARCH_LIB_DIR}; do \ Due to the fact that we rsync both 'usr' as 'usr/lib' (assuming ARCH_LIB_DIR is 'lib') we need to add the correct exclude in both cases. But the exclude is different for both. When i == 'usr', the correct exclude rule would be '--exclude lib/locale' while when i == 'usr/lib' the correct rule would be '--exclude locale'. Since we would like to avoid separate cases for this, use the following exclude: '--exclude locale/'. The trailing slash will make sure only directories called 'locale' will match. The targeted directories are then usr/lib/locale and usr/share/locale. The latter directory was not matched originally, but it should not hurt changing that.
