[bug #30] 2.14 compiling issues and atmel-ice usb not found

Hi,

Thank you for adding Atmel-ICE support to avarice, that is great news!

I was trying to compile 2.14 on a Ubuntu 18.04 machine. gcc version Ubuntu 7.5.0-3ubuntu1~18.04. packages binutils-dev libusb-dev installed for library support.

Compiled with command:

./configure
make -lusb

gcc breaks with this error:

g++ -DHAVE_CONFIG_H -I.  -Wall -Wextra   -g -O2 -MT devdescr.o -MD -MP -MF .deps/devdescr.Tpo -c -o devdescr.o devdescr.cc
devdescr.cc:36:51: error: _Pragma takes a parenthesized string literal
 PRAGMA_DIAG_IGNORED("-Wmissing-field-initializers")
                                                   ^
In file included from jtag.h:31:0,
                 from devdescr.cc:29:
pragma.h:33:38: error: ‘_Pragma’ does not name a type
 #      define PRAGMA_DIAG_IGNORED(x) _Pragma(GCC diagnostic ignored x)
                                      ^
devdescr.cc:36:1: note: in expansion of macro ‘PRAGMA_DIAG_IGNORED’
 PRAGMA_DIAG_IGNORED("-Wmissing-field-initializers")

By editing pragma.h such that it uses the pragmas for gcc version 4, it compiles, but then breaks again with this error:

jtagrw.cc: In member function ‘virtual uchar* jtag1::jtagRead(long unsigned int, unsigned int)’:
jtagrw.cc:134:13: error: cannot convert ‘bool’ to ‘uchar* {aka unsigned char*}’ in return
      return false;

Modifying this line to return NULL instead seems to solve the problem. This lead to a working binary. However, an AVR-ICE connected to the USB port is not recognized:

dev:avarice-2.12$ src/avarice --jtag usb
AVaRICE version 2.12, Nov 17 2020 09:54:27

Defaulting JTAG bitrate to 250 kHz.

did not find any USB device "usb"
USB device not found

Probably just something I am doing wrong... right?

Again, great work from you guys, keep it up!
