commit: https://git.buildroot.net/buildroot/commit/?id=9113c0cbbaa9da796fef744700425eeff34f77b3
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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
