New description:

 When building an x86_64-linux to aarch64-linux cross-compiling I get:

 {{{
 rts/StgCRun.c: In function ‘StgRun’:

 rts/StgCRun.c:756:5:
      error: unknown register name ‘%lr’ in ‘asm’
          __asm__ volatile (
 }}}

 It seems the asm code here is for iOS and does not work for Linux. Have a
 patch in progress.
