New ebuild tested + new patches: https://github.com/coffnix/coffnix-ebuilds/commit/bfd1a6e087c953d30d10d6db4ee4e0d8fa342710

The old sys-fs/hfsutils-3.2.6-r5 ebuild failed during the configure phase with GCC 14:
```
checking whether the C compiler (...) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.
```
The issue was not caused by a single patch alone. The old ebuild was still using an extremely outdated autotools setup and upstream-generated configure scripts from the original 3.2.6 release:
```
EAPI=5
inherit eutils toolchain-funcs
SRC_URI=ftp://ftp.mars.org/pub/hfs/${P}.tar.gz
```

After switching to the newer Gentoo/Debian-based hfsutils-3.2.6_p15 ebuild, the package builds correctly with GCC 14 because several important things changed simultaneously:
```
EAPI=5 -> EAPI=7
inherit eutils -> inherit autotools
upstream tarball -> Debian-maintained source + Debian patchset
```

The new ebuild also regenerates the autotools files using modern autotools:
```
eautoreconf
```

and exports the compiler environment explicitly:
```
tc-export CC
```
Additionally, newer compatibility patches were added:
```
hfsutils-3.2.6_p15-Include-string.h-for-strcmp.patch
hfsutils-3.2.6_p15-drop-manual-autoconf.patch
```

The old ebuild relied on stale configure scripts and legacy autotools logic that no longer behaves correctly with modern GCC 14 toolchains and current linker/compiler flags. The new ebuild fixes this by regenerating configure infrastructure and applying updated Debian/Gentoo compatibility patches.

Compare the old sys-fs/hfsutils-3.2.6-r5 ebuild with the newer 3.2.6_p15 ebuild and patches referenced in commit bfd1a6e087c953d30d10d6db4ee4e0d8fa342710. Start with the configure failure and its config.log, then verify that the updated package builds successfully with GCC 14 and the reported compiler flags.
