commit 9b9d2460fa949cb22597aeb16968262fa7229fae

squash! commencement: glibc-mesboot0: Support ARM.
XXX
* __restrict_arr is probably symptom of preprocessor arithmetic problems
+ lsh, /
* It looks like glibc-2.2.5 and mesboot-haeders mismatch.
+ Many __NR_* syscalls are missing
+ Some headers are missing.
* gcc-mesboot0: illegal instruction in glibc-2.2.5:
0x000276b4 <+28>: ldr r8, [r10]
0x000276b8 <+32>: svc 0x00000014
=> 0x000276bc <+36>: mov r4, r0
* gnu/packages/patches/glibc-bootstrap-arm-2.2.5.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/commencement.scm (glibc-mesboot0)[native-inputs]: Add it.
[arguments]: Apply it in apply-patches.
