-Subject: [PATCH] Makefile: fix static linking with pcre
-
-Static build with pcre is broken since version 1.19b and
-https://github.com/yrutschle/sslh/commit/cb90cc97ae64a445242e517847c6e44b7003eda4
-because -lpcre has been replaced by -lpcreposix which will result in
-the following static build failure:

-/srv/storage/autobuild/run/instance-1/output-1/host/bin/mipsel-linux-gcc -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Os   -static -static -o echosrv echosrv.o probe.o common.o tls.o  -lpcreposix -lconfig -lcap

-pcreposix.c:(.text+0x120): undefined reference to `pcre_free'

-So append -lpcre after -lpcreposix
