Config file for toolchain:
BR2_arm=y
BR2_cortex_a8=y
BR2_ARM_EABIHF=y
BR2_ARM_FPU_VFPV3=y
BR2_TOOLCHAIN_BUILDROOT_LARGEFILE=y
BR2_TOOLCHAIN_BUILDROOT_INET_IPV6=y
BR2_TOOLCHAIN_BUILDROOT_LOCALE=y
BR2_BINUTILS_VERSION_2_24=y
BR2_GCC_VERSION_4_8_X=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_ENABLE_LOCALE_PURGE=y
BR2_ENABLE_LOCALE_WHITELIST="C en_US de "


I can indeed confirm that uClibc builds crt1.o from crt1.S, using the command
line as specified in comment #7.

Looking in the binutils sources (that creates the assembler), I do find
references to ABI_VFP, but I don't see places where it is actually emitted in
the build, unless the source assembly file contains a statement
.eabi_attribute.

So the statements made by the submitter seem to be valid.
