Insert user-provided CFLAGS at the end of the command line

I'm trying to build libsqlite3-sys, which uses cc-rs on Windows, and I am running into a gcc internal compiler error. Since it happens in the DWARF area of the compiler, I would like to switch off the debug info generation. In order to do that, I set CFLAGS=-g0, however, this results in the following command line:

running: "gcc.exe" "-O3" "-ffunction-sections" "-fdata-sections" "-g0" "-g" "-fno-omit-frame-pointer" "-m64" "-DSQLITE_CORE" "-DSQLITE_DEFAULT_FOREIGN_KEYS=1" "-DSQLITE_ENABLE_API_ARMOR" "-DSQLITE_ENABLE_COLUMN_METADATA" "-DSQLITE_ENABLE_DBSTAT_VTAB" "-DSQLITE_ENABLE_FTS3" "-DSQLITE_ENABLE_FTS3_PARENTHESIS" "-DSQLITE_ENABLE_FTS5" "-DSQLITE_ENABLE_JSON1" "-DSQLITE_ENABLE_LOAD_EXTENSION=1" "-DSQLITE_ENABLE_MEMORY_MANAGEMENT" "-DSQLITE_ENABLE_RTREE" "-DSQLITE_ENABLE_STAT2" "-DSQLITE_ENABLE_STAT4" "-DSQLITE_HAVE_ISNAN" "-DSQLITE_SOUNDEX" "-DSQLITE_THREADSAFE=1" "-DSQLITE_USE_URI" "-DHAVE_USLEEP=1" "-o" "<redacted>/sqlite3.o" "-c" "sqlite3/sqlite3.c"

Note that my -g0 comes before the automatically inserted -g - this leads to it being completely ignored. To me, one of the points of having CFLAGS is to be able to insert overrides like this one. Would it be possible to insert user-provided CFLAGS at the end of the command line?

This should be fixed in version 1.0.30 - libsqlite3-sys should pull this version in automatically.

Closing since this should be fixed!
