I don't know for the upstream gcc but I did a try on my debian system and it 
is:

12:31 address@hidden ~% ls /usr/lib | grep "^crt.*"
zsh: done       ls --classify --tabsize=0 --literal --color=auto --show-
control-chars   |
zsh: exit 1     grep "^crt.*"
12:31 address@hidden ~% ls /usr/lib/x86_64-linux-gnu | grep "^crt.*"
crt1.o
crti.o
crtn.o
12:31 address@hidden ~% gcc -Wall -o test test.c

(Moving crt*.o in /usr/lib)

12:31 address@hidden ~% ls /usr/lib | grep "^crt.*"
crt1.o
crti.o
crtn.o
12:31 address@hidden ~% ls /usr/lib/x86_64-linux-gnu | grep "^crt.*"
zsh: done       ls --classify --tabsize=0 --literal --color=auto --show-
control-chars   |
zsh: exit 1     grep "^crt.*"
12:31 address@hidden ~% gcc -Wall -o test test.c

(Moving crt*.o in /)

12:31 address@hidden ~% ls /usr/lib | grep "^crt.*"                 
zsh: done       ls --classify --tabsize=0 --literal --color=auto --show-
control-chars   | 
zsh: exit 1     grep "^crt.*"
12:33 address@hidden ~% ls /usr/lib/x86_64-linux-gnu | grep "^crt.*"
zsh: done       ls --classify --tabsize=0 --literal --color=auto --show-
control-chars   | 
zsh: exit 1     grep "^crt.*"
12:33 address@hidden ~% gcc -Wall -o test test.c                    
/usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory
collect2: ld returned 1 exit status
zsh: exit 1     colorgcc -Wall -o test test.c

Attached is a patch to implement the solution you were asking for.

Best regards.
