[PATCH] Allow building Git in systems without iconv

From: Fernando J. Pereda <ferdy@gentoo.org>
Date: Feb 16, 2006, 08:38 UTC
Message-ID: <20060216083801.GB9323@ferdyx.org>

Systems using some uClibc versions do not properly support iconv stuff. This patch allows Git to be built on those systems by passing NO_ICONV=YesPlease to make. The only drawback is mailinfo won't do charset conversion in those systems.
