Inclusion of features.h for armv7-unknown-linux-gnueabihf will, in stubs-32.h, try to include stubs for hard or soft fp:

#if !defined __ARM_PCS_VFP
# include <gnu/stubs-soft.h>
#endif
#if defined __ARM_PCS_VFP
# include <gnu/stubs-hard.h>
#endif

gcc 13.3.0 as built by Yocto does not set __ARM_PCS_VFP unless -mfloat-abi=hard is set. The build will fail as stubs-soft.h may not be present.

Therefore, enable -mfloat-abi=hard when possible. gcc accepts it when an FPU is selected (-mfpu=vfpv3-d16 in this case).

eabihf corresponds to -mfloat-abi=hard, so I'm pretty sure this is correct

Bump bootstrap cc to 1.2.14 and cmake to 0.1.54

## Summary

Bump bootstrap's `cc` and `cmake` deps:

1. To make it easier to add new/unofficial targets. In particular, `cc` v1.2.4+ allows using env vars to pass target parameters to the `cc` crate. This was previously attempted in rust-lang#134344 but ran into macos-cross-to-iOS problems with `cmake` (and also rust-lang#136440, rust-lang#136720). See also discussions in rust-lang/cc-rs#1317.
2. Fix some flag inheritance warnings. Fixes rust-lang#136338.

## `cc` changelogs between `1.2.0` and `1.2.14`
