No, it is a bug introduced by your patch.

Why should it? GCC -pie option means:
1) pass -pie to the linker if it supports it
2) user appropriate startfiles and/or libraries for PIE generation

With gcc -pie -nostartfiles -nostdlibs only 1) applies, but gcc should
still do that.  Of course gcc -Wl,-pie -nostartfiles -nostdlibs will work too,
assuming ld supports -pie, but nobody should be forced to use that.
