Build on alpine

[abille]

Hi,
i was trying to build uftp 4.9.2 under alpine linux and getting the following error,
no problem with 3.7.3

gcc -g -Wall -Wextra -Wno-unused-parameter -Wno-sign-compare -Wformat=2 -Wwrite-strings -Wpointer-arith -Wcast-qual -Wshadow -Wno-missing-field-initializers -Wstrict-prototypes -Winline -Wbad-function-cast -DHAS_GETIFADDRS getconf LFS_CFLAGS -c server_common.c
getconf: LFS_CFLAGS: unknown variable
In file included from server.h:34:0,
from server_common.c:49:
uftp_common.h:173:44: warning: 'struct timeval' declared inside parameter list
int32_t diff_sec(struct timeval t2, struct timeval t1);
^

server.h:61:20: error: field 'time' has incomplete type
struct timeval time; /// Time that this client finished
^
makefile:197: recipe for target 'server_common.o' failed
make: *** [server_common.o] Error 1

i resolved it by adding #include "sys/time.h"
to client, server,proxy and uftp_common.h

best regards

Thanks for the bug report. I'll include this in the next release.
