  Set C compiler for arm.  Allow using different compiler in elf.h
  
  For arm/linux, we're building on a Raspberry Pi 5 and a 64-bit
  raspbian OS.  To build and run cmucl we needed the 32-bit compiler and
  libraries.  Hence set the compiler in Config.arm_linux appropriately.
  
  Also, let Config specify the compiler to use in elf.h.  (Untested on
  arm, of course.)  Otherwise it defaults to "gcc", basically.
  

2 changed files:

• src/lisp/Config.arm_linux
• src/lisp/elf.h

Changes:

 	$(OPENLIBM_DIR)/s_tanhf.c
