  It looks like an error when it was making the file (or else it has
error messages embedded in it); specifically, unwind-dw2-fde-glibc.o
references the abort function but it was not resolved.

  Take a look at unwind-pe.h line 76.

Consider the error messages of:

#include <stdio.h>

extern int x;

int main(int argc, char * argv[]) {

  if(argc == 2) {
    x = 2;
  }
  return 0;
}

$ gcc test.c 
/tmp/ccNyp4FK.o: In function `main':
/tmp/ccNyp4FK.o(.text+0x22): undefined reference to `x'
/tmp/ccNyp4FK.o(.text+0x2a): undefined reference to `x'
collect2: ld returned 1 exit status
