lynx: add patch to fix static link issue

Browse Source 
The lynx package incorrectly uses target LDFLAGS to build a host tool,
which causes a problem when we do a statically link build for the
target, on a host machine that doesn't support static linking.

A simple patch fixes the problematic makefile, and it has been
submitted upstream on the project mailing list.

Subject: [PATCH] src/chrtrans: don't build host tools with target LDFLAGS
In a cross-compilation context, the LDFLAGS variable contains linker
flags used when building things for the target. However, the makeuctb
tool is built for the host machine, and therefore should not use the
same LDFLAGS as the target, which is why BUILD_LDFLAGS exist.
Using LDFLAGS when building a tool for the host can cause problems
when some flags in LDFLAGS are not supported by the host machine. For
example, if you're linking statically lynx for the target, but the
build machine does not support static linking:
gcc -I../.. -I../../src -I../../src/chrtrans -I../../WWW/Library/Implementation -I../../ -static -o makeuctb makeuctb.o
/usr/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status
