cmake: Check for GNU compiler, not Linux, to set -D_GNU_SOURCE
The Debian hurd-i386 [build] failed (partly) due to -D_GNU_SOURCE not be
defined:
[215/286] /usr/bin/cc -DINCLUDE_GENERATED_DECLARATIONS -Iconfig -I../src -Isrc/nvim/auto -Iinclude -I/usr/include/luajit-2.1 -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -DDISABLE_LOG -Wdate-time -D_FORTIFY_SOURCE=2 -Wconversion -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=1 -DNVIM_MSGPACK_HAS_FLOAT32 -DNVIM_UNIBI_HAS_VAR_FROM -O2 -g -DMIN_LOG_LEVEL=3 -Og -g -Wall -Wextra -pedantic -Wno-unused-parameter -Wstrict-prototypes -std=gnu99 -Wimplicit-fallthrough -Wvla -fstack-protector-strong -fdiagnostics-color=auto -Wno-array-bounds -MD -MT src/nvim/CMakeFiles/nvim.dir/os/pty_process_unix.c.o -MF src/nvim/CMakeFiles/nvim.dir/os/pty_process_unix.c.o.d -o src/nvim/CMakeFiles/nvim.dir/os/pty_process_unix.c.o -c ../src/nvim/os/pty_process_unix.c
../src/nvim/os/pty_process_unix.c: In function 'pty_process_tty_name':
../src/nvim/os/pty_process_unix.c:121:10: warning: implicit declaration of function 'ptsname'; did you mean 'ttyname'? [-Wimplicit-function-declaration]
return ptsname(ptyproc->tty_fd);
Hurd is obviously not Linux, but it is using a GNU compiler and glibc so
it needs -D_GNU_SOURCE for the ptsname() definition to be visible.
