| Subject: [PATCH] use pkg-config to locate zlib |
| |
| AC_LIB_HAVE_LINKFLAGS can sometimes find host libs and is therefore not |
| robust when cross-compiling. Remove it for zlib and use PKG_CHECK_MODULES |
| instead. |
| |
| Removing AC_LIB_HAVE_LINKFLAGS for zlib also removes the --with-libz-prefix |
| configure option. If zlib support is enabled, then failure to find zlib via |
| pkg-config is now treated as a fatal error. |
| |
| Change based on ChromeOS gnutls 2.12.23 cross-compile fixes patch: |
