[Buildroot] [PATCH] libxml2: fix static build with xz

[Baruch Siach]

Add a patch that adds '-llzma' to the output of 'xml2-config --libs' when xz
is enabled. This fixes static build when xz is enabled.

+Subject: [PATCH] Add xz to xml2-config --libs output
+
+XML_LIBS should include LZMA_LIBS. This ensures that 'xml2-config --libs'
+shows -llzma when xz is enabled. Otherwise static link fails because of
+missing xz symbols.

Thanks.

Upstream applied this patch[1], and version 2.9.4 should be release any time 
now[2]. So I thought we'll just wait for that. This patch may still be 
considered for master though.
