[Buildroot] [PATCH 3/3] package/tqftpserv: new package

[Igor Opaniuk via buildroot <buildroot@buildroot.org>]

tqftpserv is a TFTP server over QRTR: the modem of Qualcomm SoCs fetches
files from Linux through it, e.g. the WLAN firmware (wlanmdsp.mbn) on
SoCs whose WLAN firmware runs on the modem. Files are looked up next to
the remoteproc firmware under /lib/firmware; xz and zstd compressed
files are handled when those libraries are enabled.

The systemd units are installed only with systemd as init; a sysv init
script is provided otherwise.

The patch defines _GNU_SOURCE in translate.c, which calls asprintf():
uClibc-ng declares it only then, so the build failed there (test-pkg,
bootlin-armv5-uclibc). Submitted upstream as well.

Tested on an Arduino UNO Q (Qualcomm QRB2210): the modem fetches
wlanmdsp.mbn through it and the ath10k WLAN interface comes up.

+Subject: [PATCH] translate: define _GNU_SOURCE for asprintf()
+
+asprintf() is a GNU extension. glibc and musl declare it in their
+default mode, uClibc-ng only with _GNU_SOURCE, so with uClibc-ng
+translate.c fails to build (an error with GCC 14 and later):
+
+  translate.c:298:15: error: implicit declaration of function 'asprintf'
+
+Define _GNU_SOURCE before the includes, as xz-decompress.c and
+zstd-decompress.c already do.
