[gdb] Fix -Wstrict-null-sentinel warning (--with-iconv-bin)
When using configure flag --with-iconv-bin=$(which iconv), we run into: ... gdb/charset.c: In function 'void find_charset_names()': gdb/charset.c:821:75: error: missing sentinel in function call [-Werror=format=] iconv_program = concat (iconv_dir.c_str(), SLASH_STRING, "iconv", NULL); ^ cc1plus: all warnings being treated as errors ... Fix the warning. Build and reg-tested on x86_64-linux. 2020-02-12 Lukas Durfina <ldurfina@tachyum.com> Tom de Vries <tdevries@suse.de> * charset.c (find_charset_names): Cast concat NULL sentinel to char *.
