[libmicrohttpd] Borked build in doc/example for 0.9.26

[Anthony G. Basile]

Hi everyone,

libmicrohttpd-0.9.26 has a build problem.  doc/examples/sessions.c makes 
calls to MHD_destroy_post_processor and friends, but it is not bracketed 
by if HAVE_POSTPROCESSOR ... endif in doc/examples/Makefile.am leading 
the the following link time error when --disable-postprocessor.

libtool: link: x86_64-pc-linux-gnu-gcc -fno-strict-aliasing -O2 -pipe 
-Wl,-O1 -Wl,--as-needed -o .libs/sessions sessions.o 
../../src/daemon/.libs/libmicrohttpd.so -lrt -lpthread
sessions.o: In function `request_completed_callback':
sessions.c:(.text+0x33): undefined reference to `MHD_destroy_post_processor'
sessions.o: In function `create_response':
sessions.c:(.text+0x29e): undefined reference to `MHD_post_process'
sessions.c:(.text+0x2cd): undefined reference to 
`MHD_destroy_post_processor'
sessions.c:(.text+0x3ea): undefined reference to `MHD_create_post_processor'
collect2: ld returned 1 exit status


Its fixed by the following patch.  Sorry for inlining it, but its pretty 
obvious:
