GDB: maint: Fix build on FreeBSD
While trying to build current trunk of GDB on FreeBSD 14.3 on aarch64,
I hit this warning converted to an error:
In file included from /home/bauermann/src/binutils-gdb/gdb/maint.c:37:
/home/bauermann/src/binutils-gdb/gdb/maint.h:64:8: error: private field 'm_start_space' is not used [-Werror,-Wunused-private-field]
64 | long m_start_space;
| ^
1 error generated.
gmake[2]: *** [Makefile:1973: maint.o] Error 1
I used the default compiler on this system:
$ c++ --version
FreeBSD clang version 19.1.7 (https://github.com/llvm/llvm-project.git llvmorg-19.1.7-0-gcd708029e0b2)
Target: aarch64-unknown-freebsd14.3
Thread model: posix
InstalledDir: /usr/bin
The problem is that the only two places that use m_start_space are
guarded by HAVE_USEFUL_SBRK, so also guard the member declaration with
it.
Build-tested on aarch64-unknown-freebsd14.3.
