package/libxml-parser-perl: use the compiler as "LD"

Since commit efa95b19aeab6bdcd7d5a620e199c2c32cf2516b
("package/libxml-parser-perl: make host build use correct compiler"),
we pass $(HOST_CONFIGURE_OPTS) when building host-libxml-parser-perl,
in order to use the correct host compiler.

However, this means that LD="$(HOSTLD)" is passed. However, the
host-libxml-parser-perl passes compiler arguments to LD, so it really
assumes that LD is gcc, not ld. For example, it tries to pass
-mtune=generic.

So, let's tell host-libxml-parser-perl that LD is "$(HOSTCC)".
