Since Binutils 1a9ccd70f9a7[1] u-boot will not link targets that set CONFIG_SYS_TEXT_BASE=0 with the following error:
LD u-boot arm-linux-gnueabi-ld.bfd: u-boot: Not enough room for program headers, try linking with -N arm-linux-gnueabi-ld.bfd: final link failed: Bad value
The issue can reproduced the bad binutils and the rock2_defconfig target.
This issue was also encountered by the powerpc kernel[2], with the fix being to pass --no-dynamic-linker for linkers newer than 2.26 when this flag was introduced. The option tells ld that the PIE or shared lib does not need loaded program headers.
Ubuntu Zesty's Binutils 2.27.51.20161202 hits this error.

Signed-off-by: Joel Stanley joel@jms.id.au --- v2: - use ld-option to test for the flag instead of the version, as suggested by Måns - update commit message with clarification from Alan
