I discovered that if I move crt1.o, crti.o and crtn.o to my build directory on 
the target system where the C source lives, the test.c file compiles 
correctly. 

Looking at the gcc-v output, gcc is expecting these files to be in the build 
directory, not in /usr/lib! 

What changes would be required to gcc- gcc-uclibc-3.x.mk to resolve this so 
that /usr/lib/crtX.0 files can be brought in from /usr/lib?


Here's the output of gcc -v test.c:

GNU assembler version 2.16.1 (i586-linux-uclibc) using BFD version 2.16.1
 /usr/libexec/gcc/i586-linux-uclibc/3.4.2/collect2 --eh-frame-hdr -m elf_i386 
-dynamic-linker /lib/ld-uClibc.so.0 crt1.o 
crti.o /usr/lib/gcc/i586-linux-uclibc/3.4.2/crtbegin.o
